Google Cloud VMs on AMD Turin chips need a guest OS patch and a stop-and-start to protect against three CPU side-channel flaws, Google said this week. The company has already applied mitigations against attacks between VMs, and between VMs and the host. Inside a VM, the flaws may let an attacker with code on the same processor core infer data from other processes or the kernel. The affected
Security teams have more alerts, logs, and monitoring tools than ever. Yet when an attack happens, one simple question can still take too long to answer: Who or what is behind this activity, and what can they access? A suspicious login might belong to an employee. An unusual API call could come from a machine account. Or an AI agent might be accessing sensitive systems using permissions nobody
N-able on Thursday said it's investigating a new public disclosure containing claims of additional vulnerabilities in on-premise versions of N-central running version 2026.4.1 HF2. "Based on our initial review, the server issue described depends on a non-default configuration in which the Legacy API is turned on and exposed to the public internet," N-able said in a new advisory.

Since mid-August 2026, a phishing operation has been stealing live Google sessions from corporate users. Every check defenders normally lean on to judge a link came back clean, and the operator designed it that way on purpose. The Threat Research team at Material Security spotted the campaign and has since taken down hundreds of attacker domains in an effort the team calls Operation CloudFire.
PTC has released patches for a new critical vulnerability impacting Windchill and FlexPLM software that, if successfully exploited, could result in remote code execution. The security flaw, tracked as CVE-2026-126325, carries a CVSS v4 score of 9.2 out of a maximum of 10.0. It has been described as a case of improper input validation and deserialization of untrusted data that could result in
A critical flaw in MongoDB Server allows an unauthenticated attacker to send two requests that trigger a crash on the database server. The crash occurs only if that server is later chosen to take over as the main server while it still lacks some recent changes. MongoDB, the company that makes the database, released fixed versions earlier this week. The affected servers are members of a replica
A flaw fixed in Node.js this week lets unauthenticated clients crash servers that use the runtime's built-in HTTP/2 support on the 24.x and 26.x release lines. A second HTTP/2 flaw can cause a server to send a client pieces of its memory, including responses intended for other connections. Fixed versions were released for all three supported lines: 22.23.5, 24.22.3, and 26.13.1. The crash

Of the 37,571 Grok-built apps that security company Claroc found online, 35,578 were open to anyone without a sign-in, the researchers said yesterday. They included 24 apps built by staff at the social network X and at SpaceXSI, the company that makes the Grok AI assistant. Most of the open apps were games, landing pages, and calculators, but about 1 in 10 contained internal business or
We tell customers three things about securing AI agents: they need their own identities, access that fits the job they’re given, and traceability that’s separate from any human’s. That was true for us at Token as well. Then, we built an agent that broke all three by default. This helped us think through how such agents should be defended. When a browser agent acts inside a user’s authenticated
The in-house Python script behind eMudhra's October key compromise has now cost the company 8 more of its intermediate certificate authorities (CAs), even though it did not weaken their keys. Each intermediate CA has its own private key, which the company uses to sign the certificates it issues. The 8 intermediate CAs compromised in October had a different problem: a single line in the script

An AI model can be given a hidden backdoor by editing fewer than 10 of its rarely used neurons, without retraining the model, Microsoft researchers have shown. When a chosen trigger appears, the model outputs an attacker's command, which an agent using that model would run with the agent's own permissions. The attacker must be able to change the model's weights. The team tested the method on

### Impact 0.31.0 fixed GHSA-6f4g-xm8v-pgv6, where text from a Compose file became GitHub Actions workflow commands in compose-lint's output. The fix escapes the command openers in compose-lint's own output, but not in the argument parser's error messages. When a repository path reaches compose-lint's arguments without a -- before it, the argument parser prints it raw in its error message. That includes a carriage return, which the runner treats as a line break, so a command can also start a new line there. A pull request can therefore create annotations, fold or hide parts of the job log, or issue other commands the runner accepts, when CI runs compose-lint over it, before anyone reviews it.

In v0.31.0 that message is outside the window in which the Action turns command processing off, and v0.30.0 has no such window. A pull request can commit a symlink on that path to a directory whose name contains a newline followed by a command. A pull request can therefore create annotations, fold or hide parts of the job log, or issue other commands the runner accepts, when CI runs compose-lint over it, before anyone reviews it. The pass/fail result is not changed. Only the Action is affected, and only when sarif-file: points into a subdirectory. The documented setup, sarif-file: results.sarif at t…
### Impact 0.31.0 fixed GHSA-6f4g-xm8v-pgv6, where text from a Compose file became GitHub Actions workflow commands in compose-lint's output. --format json and --format sarif output never passed through that fix, so ##[ inside a service name or other value reaches the log intact when the output is printed to stdout rather than written to a file. The runner acts on ##[ in the middle of a line, so the JSON layout does not prevent it. A pull request can therefore create annotations, fold or hide parts of the job log, or issue other commands the runner accepts, when CI runs compose-lint over it, before anyone reviews it. The pass/fail result is not changed. Affected setups print JSON or SARIF output to a CI log from the compose-lint package, the pre-commit hook or the Docker image.…
### Impact ActiveStorage::Blob#open writes a blob to a tempfile whose name carries the extension of the uploaded filename, and hands that path to ffprobe (VideoAnalyzer, AudioAnalyzer), ffmpeg (VideoPreviewer) and ImageMagick (ImageAnalyzer, the :mini_magick variant processor). These tools select a decoder from the file extension when the content does not identify its own format, so an attacker who chooses the filename and declares the content type of an upload chooses which decoder processes it. An FFmpeg built with AviSynth support treats a file with the .avs extension as an AviSynth script and evaluates it, which could disclose files readable by the application process through the preview image, or load a native library the attacker has also uploaded, possibly leading…
### Impact ActiveStorage::Service::GCSService#url_for_direct_upload does not bind the declared content length into the signed direct-upload URL, and #headers_for_direct_upload returns no length constraint, so the URL authorizes an upload body of any size. A direct-upload client could store a file larger than the byte_size it declared, and the resulting blob keeps the declared size, possibly bypassing application file size validations and quotas. This is the weakness that CVE-2020-8162 fixed in the S3 service. Applications that store files in Google Cloud Storage and accept direct uploads are affected. ### Details The fixed releases sign an x-goog-content-length-range header that matches the blob's declared byte_size and return it from headers_for_direct_upload, so Cloud Storag…
### Impact When constant lookup raises LoadError, ActiveSupport::Inflector#safe_constantize (and String#safe_constantize) builds a regular expression from the requested constant name without escaping it, so a caller that passes untrusted input lets the attacker choose the source of a pattern that the application compiles. Crafted patterns can trigger defects in Ruby's regular expression compiler, possibly leading to a crash of the server process, and repeated requests could keep the application unavailable. Action Cable passes the channel value of each subscribe command to safe_constantize before any channel lookup, so in the default configuration an unauthenticated client of the Action Cable endpoint can reach this code. ### Details The check that decides whether `safe_consta…

### Impact ActiveStorage::Filename#base and #extension_with_delimiter, and therefore #extension, pass the stored filename unmodified to File.basename and File.extname, which raise ArgumentError when the name contains a NUL byte. Active Storage stores the client-supplied filename verbatim, so a user who is permitted to upload an attachment could persist such a filename on databases that accept NUL bytes in string columns, such as SQLite and MySQL/MariaDB. Each subsequent request that builds a variant or preview of the blob, opens it, or renders it as an Action Text attachment then raises, possibly resulting in a persistent DoS vulnerability for the pages that display the blob until it is purged or its filename is corrected. Applications that use PostgreSQL are not affected, bec…

### Impact The Action Mailbox Mailgun ingress authenticates a request with an HMAC of the timestamp and token parameters concatenated without a separator, and ActionMailbox::Ingresses::Mailgun::InboundEmailsController::Authenticator#recent? rejects only timestamps more than 2 minutes in the past. Because the signature does not fix the boundary between the two values, a captured signed request can be presented with a timestamp far in the future, which the ingress then accepts indefinitely. An attacker who obtains one signed Mailgun webhook request, but not the signing key, could submit arbitrary inbound email that Action Mailbox processes as genuine, possibly leading to forged messages attributed to the sender of the attacker's choosing. Applications that receive inbound email throug…
### Impact ActiveSupport::MessagePack serializes an ActiveSupport::SafeBuffer as its bytes alone and deserializes it as a new SafeBuffer, so a buffer that is no longer html_safe? (for example, one mutated in place with gsub!) is restored as html_safe. If such a buffer holds untrusted input and is stored through a MessagePack serializer, rendering it after it is loaded bypasses ERB auto-escaping, possibly leading to XSS. Applications on Rails 8.1 are affected if they use a MessagePack serializer, such as config.action_dispatch.cookies_serializer = :message_pack or :message_pack_allow_marshal, or serializer: :message_pack for Rails.cache, ActiveSupport::MessageVerifier or ActiveSupport::MessageEncryptor, and store a SafeBuffer that was mutated in place with untrust…
### Impact Action Pack negotiates the format of a rendered response from the Accept, X-Requested-With and, for XHR requests without Accept, Content-Type request headers, but ActionController::Rendering#_set_vary_header adds Vary: Accept only when the request carries a usable Accept header and the response has no Vary header yet. A response to a request without Accept, or to an XHR request, therefore omits the headers that selected its representation, and a response whose Vary the application set before rendering (for example Vary: Accept-Language) never gains Accept. A shared cache that honours Vary could store such a response and serve it to later clients that request a different representation, possibly leading to cache poisoning in which visitors receive, unti…
### Impact Action Pack session stores other than ActionDispatch::Session::CookieStore (CacheStore, MemCacheStore, and third-party stores built on AbstractStore, AbstractSecureStore or the session mixins) write the session cookie without a SameSite attribute, regardless of config.action_dispatch.cookies_same_site_protection, which defaults to :lax. Only CookieStore applies the configured policy. In browsers that do not treat a cookie without the attribute as SameSite=Lax, a cross-site request could carry the session cookie, possibly leading to cross-site request forgery against actions that do not verify an authenticity token, such as those of API-only applications. Applications are affected when they use a session store other than CookieStore and do not pass `same_si…
### Impact When Active Storage serves a file through its proxy controllers, ActiveStorage::Streaming#send_blob_stream handles an error from the storage service by calling head to send a 404 or 500 response. If the error occurs after the first chunk has been written, the response is already committed, and head replaces the response body while the server is still reading the original ActionController::Live buffer. That buffer is never closed, so the server thread handling the request blocks until the process restarts. Repeated failed downloads could exhaust the server's threads, possibly resulting in a DoS vulnerability. Applications are affected when they store files on a service that streams a download in several requests, such as Amazon S3, an S3-compatible service or Google Clou…
### Impact Since Rails 8.1.0, ActionDispatch::RemoteIp derives request.remote_ip from Rack::Request#forwarded_for, which under Rack 3 reads the RFC 7239 Forwarded header in preference to X-Forwarded-For. When a reverse proxy appends the client address to X-Forwarded-For but passes a client-supplied Forwarded header through unchanged, request.remote_ip returns an address chosen by the client, and the IP spoofing check does not raise, because it compares only Client-Ip with the forwarded addresses. An unauthenticated attacker could therefore spoof request.remote_ip, possibly bypassing IP-based access controls and rate limits keyed on the client address (including the default by: of rate_limit), and falsifying the client address in logs. ### Details The 8.1.0 change (…
### Impact ActionDispatch::Session::CacheStore writes a session back to the cache at the end of each request that loaded it, without checking that the session's cache entry still exists. When a concurrent request destroys the session, through reset_session on logout or by deleting its cache entry on the server, a request that loaded the session earlier and finishes later restores it under its original session ID. Logout and server-side revocation could therefore fail to end a session, and an attacker who holds a stolen session cookie could keep that session valid across the victim's logout. Applications that use config.session_store :cache_store are affected, with any cache backend. ActionDispatch::Session::CookieStore is not affected, nor is `ActionDispatch::Session::MemCacheStor…
### Summary ed25519.verify() does not reject public keys of small order, such as the identity point. Under such a key, a signature with S = 0 and a small-order R verifies for many messages, or for every message with the identity key, without any private key. Fixed in node-forge 1.4.3. ### Details crypto_sign_open() in lib/ed25519.js decodes the public key A with unpackneg(), which only checks that the point is on the curve, and then checks R == [S]B - [k]A with k = SHA-512(R || A || M). Nothing rejects public keys of small order: the identity point, the other 7 points of order 2, 4 or 8, and their non-canonical encodings with y >= p. With S = 0, the check becomes R == [k](-A). For a small-order A, [k](-A) is one of at most 8 small-order points, so an attacker c…
### Summary A forge.tls client accepts any compression method in the ServerHello, although it only offers no compression. An unknown method makes connection.process() throw an uncaught Error when the client handles ServerHelloDone, before the server is authenticated. A malicious server or an on-path attacker can use this to terminate a Node.js process. Fixed in node-forge 1.4.3. ### Details The client's ClientHello offers only the null compression method. tls.parseHelloMessage() in lib/tls.js stores the ServerHello's compression_method for the client without checking it (the code has a TODO: handle compression methods). When the client handles ServerHelloDone it calls tls.createConnectionState(), which throws Error('Unsupported compression algorithm.') for any method o…
forge.http trims response header and Set-Cookie values with the regular expression /\s*$/, which takes quadratic time on a long run of whitespace followed by another character. A server or on-path attacker can block a forge.http client for minutes with one large response header. Fixed in node-forge 1.4.3. ### Details _trimString() in lib/http.js removes trailing whitespace with str.replace(/\s*$/, ''). On a string of n whitespace characters followed by a non-whitespace character, the regular expression engine tries a match at each of the n positions and scans the rest of the run each time, so the work is O(n^2). forge.http calls _trimString() on every response header value read by response.readHeader(), and again on cookie names and values in response.getCookies(). T…
### Summary A forge.tls client throws an uncaught TypeError from connection.process() when it receives a ServerHello while it has no session: after a close_notify alert or a call to close(), or before handshake() is called. A malicious server or an on-path attacker can use this to terminate a Node.js process. Fixed in node-forge 1.4.3. ### Details tls.handleHandshake() in lib/tls.js updates the handshake digests with c.session.md5.update(bytes) before it calls the message handler. A client creates its session in handshake(), and c.reset() sets it to null when the connection is closed. Closing doesn't set the fail flag, and the client goes back to expecting a ServerHello, so a Handshake record received afterwards still reaches handleHandshake(), which throws `Type…
### Summary With the non-default stopNodes option, a stop node's body with many "" anywhere after makes readStopNodeData() rescan the entire remaining input from every "
### Summary Mongoose chooses which discriminator model or schema to use by looking up the discriminator key value (__t by default) in a plain object of registered discriminators, for example Model.discriminators[doc.__t]. That value comes from user documents and query filters. Because the lookup did not check own properties, a value that names a property inherited from Object.prototype resolves to that inherited value instead of a discriminator. Examples are 'constructor', 'toString' and 'hasOwnProperty'. - __t: 'constructor' resolves to the global Object function. Mongoose then calls new Object(doc), which returns the raw user object where a Mongoose document is expected. - __t: 'toString' and similar names resolve to built-in functions that throw when used as a const…
### Summary Three Mongoose code paths copy data into objects by property name without checking whether the property is the object's own or inherited from its prototype: 1. Loading a document from the database (init(), also used by Model.hydrate()) 2. Setting a dotted path on a document ($__set, used by new Model(obj), doc.set() and doc.$set()) 3. Merging update documents (utils.mergeClone, used by findOneAndReplace(), chained update calls and Query.prototype.merge()) When a key names an inherited property, such as toString or valueOf, or a document internal such as $__schema, Mongoose writes into the shared object behind that property. The data comes from the attacker. - **Denial of service.** For example, { "toString": { "call": 1 } } overwrites `Object.prototyp…
### Summary On JRuby, the NONET parse option did not block an external DTD or entity whose system identifier used a short-form IPv4 host, such as http://127.1/ or http://169.254.43518/, or was an absolute path such as /x.dtd in a document parsed from a network URL. An application that parses untrusted XML with DTDLOAD, DTDVALID or NOENT could be made to send network requests, potentially enabling SSRF. Nokogiri 1.19.5 applies the XML::Schema check from [GHSA-8678-w3jw-xfc2](https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-8678-w3jw-xfc2): with NONET set, only local resources are loaded. Only JRuby is affected. Default parse options are not affected. ### Severity The Nokogiri maintainers have evaluated this as low severity. ### Mitigation Upgrade to Noko…
### Summary Nokogiri's CRuby native extension could leave a Ruby wrapper pointing to freed memory when replacing the value of an existing XML attribute via Nokogiri::XML::Node#[]= or Nokogiri::XML::Node#lang=. If Ruby code had already accessed the attribute's child nodes, replacing the value could free those native child nodes while their wrappers remained reachable. Using one of those child nodes afterwards could cause an invalid read and a possible segfault. This is the same class of issue as [GHSA-phwj-rprq-35pp](https://github.com/sparklemotion/nokogiri/security/advisories/GHSA-phwj-rprq-35pp), which was fixed for Attr#value= in Nokogiri 1.19.4. Nokogiri 1.19.5 preserves all already-wrapped attribute child nodes before replacing the attribute value. JRuby is not affected. ### Se…
### Summary Nokogiri's HTML5 serializer did not escape text inside noscript elements, or `` inside attribute values. When a document parsed with the default options is serialized, a browser with scripting enabled can parse the output into markup that Nokogiri's parser never produced. This is a mutation XSS for applications that sanitize untrusted HTML with Nokogiri::HTML5, allow noscript elements, and send the serialized output to browsers. Nokogiri 1.19.5 escapes both, as the HTML standard's serialization algorithm requires. Text inside noscript is still emitted unescaped for documents parsed with parse_noscript_content_as_text: true. Only the C extension (CRuby and TruffleRuby) is affected. JRuby does not implement Nokogiri::HTML5. ### Severity The Nokogiri maintainers have…
### Summary Prototype pollution via Schema.prototype.virtual() — the 2022 fix for CVE-2022-2564 / CVE-2022-24304 protected Schema.path()/add() but never virtual(), so the same class of bug is still exploitable in all maintained release lines. ### Details In lib/schema.js, Schema.prototype.virtual() (defined at line 2643) builds the virtual path via: ``javascript virtuals[name] = parts.reduce(function(mem, part, i) { mem[part] || (mem[part] = (i === parts.length - 1) ? new VirtualType(options, name) : {}); return mem[part]; }, this.tree); // lines 2755-2759 `` Unlike path()/add(), virtual() never received the specialProperties check added for CVE-2022-2564/CVE-2022-24304 (lib/schema.js lines 806, 1308, 1331). A path containing __proto__/constructor/prototype segments reso…
### Summary sanitizeFilter exists to stop query selector injection: it wraps operator objects such as { $ne: null } in filter values in $eq, so they are matched literally. Set on a connection with mongoose.connect() or createConnection(uri, { sanitizeFilter: true }), the connection reports it as enabled but queries never apply it. An application that relies on the connection-level option and passes an attacker-controlled object into a filter therefore remains open to selector injection, and a password value of { $ne: null } returns the account record without the password. ### Details NativeConnection#createClient() at lib/drivers/node-mongodb-native/connection.js:270-272 moves options.sanitizeFilter into Connection.config and deletes the original option. `Query#_castCond…
### Impact sanitizeFilter is Mongoose's mechanism for protecting against query selector injection attacks. In older versions of Mongoose, sanitizeFilter was not applied for countDocuments() queries. ### Patches Patches have been released for all supported Mongoose major release lines. Please upgrade to the following versions depending on which major version of Mongoose applications are using. 1. ^9.9.2 2. ^8.24.3 3. ^7.8.12 4. ^6.13.11 ### Workarounds Middleware: ``javascript mongoose.plugin(function() { schema.pre('countDocuments', function() { // This will always apply sanitizeFilter on countDocuments mongoose.sanitizeFilter(this.getFilter()); }); }); ``
## Summary Rack::Multipart::Parser reads the request body in chunks of rack.multipart.buffer_size (1 MiB by default) into an internal scan buffer. Parsed bytes are only discarded from that buffer when a chunk ends inside a part body. A request whose parts are sized so that every chunk ends inside, or immediately after, a part's headers is never compacted, so the buffer grows to the size of the request. This results in a denial of service condition through memory exhaustion for applications that parse multipart requests. ## Details The parser appends each chunk read from the input to a StringScanner and advances through boundaries, headers, and bodies. In the body state, when no closing boundary is found, the consumed prefix is removed before more data is read. In the header state, a…
## Summary The guard added for CVE-2026-26961 (GHSA-vgpv-f759-9wx3), which rejects multipart requests with more than one boundary parameter, only inspects the part of the Content-Type header after the boundary it extracts. A Content-Type whose first boundary parameter is empty or begins with a quote, semicolon, or comma is skipped by the extraction pattern, so a second boundary parameter is accepted silently and Rack parses the body with a boundary that a conforming parser would not derive from the header. ## Details Rack::Multipart::Parser.parse_boundary extracts the boundary with a regular expression that uses a lazy prefix and a value class excluding ", ;, and ,. For a header such as multipart/form-data; boundary=";boundary=AaB03x" or `multipart/form-data; boundary=…
A flaw in Git can let a malicious repository run an attacker's code on a computer that clones it recursively, together with its submodules. The Git project fixed it this week in Git 2.56.1, with matching fixes for the 2.50 through 2.55 series in 2.50.2, 2.51.3, 2.52.1, 2.53.1, 2.54.1 and 2.55.1. The flaw, tracked as CVE-2026-111760, is an integer truncation in how Git handles its index. An
### Summary A Server-Side Request Forgery vulnerability exists in NocoBase v2.1.10 in the @nocobase/plugin-action-custom-request plugin. A low-privileged authenticated user can call the customRequests:send endpoint and override the stored request URL at runtime using options.url. This causes the NocoBase server to perform outbound HTTP requests to attacker-controlled or internal URLs. * Product: NocoBase * Version: v2.1.10 * Component: @nocobase/plugin-action-custom-request * Severity: Moderate * Required privilege: authenticated low-privileged user / member Testing was performed only in a local Docker lab environment at http://127.0.0.1:13000. No public NocoBase instance was tested. Lab environment: * Docker image: nocobase/nocobase:latest-full * Commit: `23e2bd35625439594e47…
An attacker exploited a remote code execution flaw in SGLang, an open-source inference engine, and ran code on one of NEAR AI's inference servers last Sunday. The attacker could also have seen requests being processed on that server that day, including requests sent in confidential mode, the company said earlier this week. That mode processes requests inside a trusted execution environment (TEE
## Summary Rack::Request#host_with_port, and therefore #base_url and #url, return the raw authority string when it fails validation. An attacker-controlled Host, X-Forwarded-Host, or Forwarded: host= value containing characters that are not permitted in an authority is embedded verbatim in URLs generated by the application. This completes the fix for CVE-2026-34835 (GHSA-g2pf-xv49-m2h5), which made #host and #hostname return nil for an invalid authority but left this path unchanged. ## Details Rack::Request#host_with_port splits the authority with split_authority. When the AUTHORITY pattern does not match, no components are returned and host_with_port falls back to returning the unvalidated authority string. base_url is "#{scheme}://#{host_with_port}" and `ur…
## Summary Rack::Static normalizes the request path with Utils.clean_path_info when deciding which file to serve, but matches header_rules against a path that is only URL-decoded. A request containing dot segments, raw or percent-encoded, is served the normalized target file while the header rules for that file's location are not applied. This allows an attacker to receive a protected static file without the security headers configured for it. ## Details Rack::Static#call computes the served path as Utils.clean_path_info(Utils.unescape_path(path)). Rack::Static#applicable_rules applies only Utils.unescape_path before testing string and regular expression rules. A request for /assets/../uploads/file.html or /assets/..%2fuploads/file.html is served as uploads/file.html,…
### Impact 0.31.0 fixed GHSA-6f4g-xm8v-pgv6, where text from a Compose file became GitHub Actions workflow commands in compose-lint's output. The fix escapes the command openers in everything compose-lint prints, and the 0.31.0 changelog says the report "escapes both openers (also covering Azure Pipelines)". Five paths were left open: - **Unicode whitespace before a line-leading ::.** The runner strips all Unicode whitespace from the start of a line before it looks for a command. compose-lint only accounted for spaces and tabs, so a no-break space or another Unicode space ahead of :: is not escaped. It can come from a Compose value, or from a file name: the text report's file heading and per-file summary, and the fix summary on stderr, start with the path as given, so a directory na…

### Summary An XSS (Cross-Site Scripting) vulnerability occurs when an attacker is able to inject their own JavaScript code into a web page's source, which is subsequently processed by the victim's browser. A common cause of this vulnerability is the failure to validate user-supplied data before displaying it within the vulnerable application without proper filtering. To exploit the vulnerability, an attacker must input HTML code into a vulnerable parameter containing structures that trigger the execution of JavaScript. The DOM XSS variant occurs when user-supplied data is processed by a client-side script; if this data is not handled correctly by the script itself, it becomes possible to inject additional JavaScript commands. **Attacker model:** Any actor who can get a DICOM object in fr…
### Summary When verifying a certificate, node-forge chose the RSA padding scheme (PKCS#1 v1.5 or RSASSA-PSS) and PSS parameters from the issuer certificate's own signature algorithm instead of the certificate being verified. A certificate labeled as signed with RSASSA-PSS could pass verifyCertificateChain() with a PKCS#1 v1.5 signature. Fixed in node-forge 1.4.1. ### Details certificate.verify(child) in lib/x509.js hashes the child's TBSCertificate with the digest of the child's signature algorithm, then calls _verifySignature() with the issuer certificate. _verifySignature() selected the padding scheme from that certificate's signatureOid and signatureParameters, so the child was verified with the issuer's own scheme rather than the one the child declares. As a result, a c…
### Summary decipher.finish() in CBC and ECB mode accepted malformed PKCS#7 padding: only the last byte was checked, against a limit of four blocks, so mismatched padding bytes, a zero count and oversized counts were accepted and up to four blocks of plaintext could be silently removed. Fixed in node-forge 1.4.1. ### Details modes.cbc.prototype.unpad() and modes.ecb.prototype.unpad() in lib/cipherModes.js read the last decrypted byte as the PKCS#7 padding count, rejected it only if it was larger than `blockSize
### Summary forge.pki.verifyCertificateChain() enforces the pathLenConstraint of a CA certificate's basicConstraints extension only when that certificate also has a keyUsage extension. For a CA certificate with a pathLenConstraint and no keyUsage, chains with more intermediate CA certificates below it than the constraint allows are accepted. Fixed in node-forge 1.4.1. ### Details In pki.verifyCertificateChain() (lib/x509.js), the path length check for a CA certificate was guarded by keyUsageExt !== null && 'pathLenConstraint' in bcExt. The keyUsage test was originally a proxy for "a basicConstraints extension exists". Since node-forge 1.4.0 (GHSA-2328-f5f3-gj25), basicConstraints is required for every certificate that reaches this check, so the only remaining effect of…
### Summary asn1.fromDer() decodes the contents of BIT STRINGs as ASN.1 by default. That decode ignored the maxDepth recursion limit (an incomplete fix of CVE-2025-66031) and also decoded nested BIT STRINGs, keeping a full copy of the decoded contents at each level, so small crafted DER or PEM inputs (certificates, keys, PKCS structures) use excessive CPU time and memory and can abort the Node.js process. Fixed in node-forge 1.4.1. ### Details asn1.fromDer() attempts by default to decode the contents of primitive BIT STRINGs as ASN.1 (decodeBitStrings, default true). Two flaws in that decode in lib/asn1.js allow resource exhaustion: 1. _fromDer() started the BIT STRING decode with a new options object, {strict: true, decodeBitStrings: true}, that did not include maxDepth…
### Summary RSASSA-PKCS1-v1_5 signature verification (publicKey.verify() with the default scheme, also used by X.509 certificate and PKCS#7 verification) accepted non-canonical BER encodings of the DigestInfo, such as NULL parameters with content and non-minimal lengths. These leave attacker-controlled bytes inside an accepted DigestInfo, which allows signatures to be forged without the private key for RSA keys with a low public exponent (e=3). Fixed in node-forge 1.4.1. ### Details In lib/rsa.js, key.verify() with the default RSASSA-PKCS1-V1_5 scheme removes the padding, parses the recovered DigestInfo with the lenient BER parser asn1.fromDer() and checks its structure with asn1.validate() against digestInfoValidator. Neither requires a canonical DER encoding, so verificati…
### Impact The name, domain, and path fields of makeCookie() were validated with a regex that allows ;, the attribute separator in Set-Cookie headers. Because serializeCookie() writes those fields verbatim, a caller who passes untrusted input into any of them can append arbitrary attributes to the header. For example, a domain of "legit.com; Domain=.parent.tld" serializes to session=token; Domain=legit.com; Domain=.parent.tld. RFC 6265 §5.3 takes the last occurrence, so the injected domain wins and the cookie widens to the parent domain. The same trick sets SameSite=None or Max-Age when the caller has not set those options itself. The value field is unaffected: it passes through encodeURIComponent, which encodes ;. CR and LF are rejected by the existing regex…
## Impact OctoPrint versions 2.0.0rc1 up until version 2.0.0rc6 are susceptible to cross-site scripting via a specially crafted default port or baudrate setting on the bundled Serial Connector plugin, supplied via the API as new defaults during a connect request. ## Patches The vulnerability is patched in 2.0.0rc7. ## Workaround Check config.yaml for Javascript fragments in printerConnection.preferred.parameters.port or printerConnection.preferred.parameters.baudrate. If found, remove them. You can check who of your users had access to your instance since you flashed 2.0.0rc1 or above via auth.log. ## Credits This vulnerability was discovered and responsibly disclosed to OctoPrint by "mahn-don". ## Timeline 2026-10-14: Report received 2026-10-14: Report acknowledged 2026-10-…
### Summary Altair 8.5.7 accepts plugin configuration directly from the iframe-sandbox query string. When plugin_sandbox_opts contains type: "scripts" and an attacker-controlled URL in scriptUrls, the sandbox page creates a classic `` element and loads the supplied script. In the intended plugin flow, this page runs inside an `` without allow-same-origin, giving plugin code an opaque origin. However, if a victim opens the crafted sandbox URL directly, that iframe isolation is absent and the attacker-controlled script executes in the origin serving Altair, resulting in DOM-based cross-site scripting (XSS) / arbitrary JavaScript execution in the Altair hosting origin. Exploitation requires the victim to open a crafted URL. ### Details The sandbox reads its configuration directly…
### Summary fastMerkleRoot pads an odd level by hashing the last node with itself. It does not report that it did so, and checkTxRoots never looks for repeated transactions. A peer can therefore duplicate transactions to fill the pad and produce a block with a different transaction list but the same merkle root. The block hash and block id do not change, so the header still carries valid proof of work. In the proof of concept a real mainnet block goes from nine transactions to ten, and separately to twelve, with the same id every time, and checkTxRoots accepts all three. Bitcoin Core rejects this case through the mutated flag in ComputeMerkleRoot and the bad-txns-duplicate reason in CheckBlock. This is CVE-2012-2459. ### Details A bitcoin merkle tree pads an odd level by has…
### Impact This is an incomplete fix for GHSA-jf3h-8jvx-vcrg. 0.32.0 made findings quote the ${NAME} a sibling .env filled in, instead of its value. The same release added a stop at 20,000 findings per document, and that stop is checked before the quoting step. A run that hits it reports the findings graded so far with the resolved values still in them, in text, JSON and SARIF output. That happens with or without --allow-partial-coverage. The attack is the one GHSA-jf3h-8jvx-vcrg describes. In a CI workflow that writes secrets into the .env beside the Compose file, a pull request changes a line to image: "${DB_PASSWORD}". It also pushes the document past 20,000 findings, which a few hundred lines can do, because an aliased list is graded once for each service that uses it. The s…
### Impact An authenticated non-administrative user could access a Kubernetes cluster they are not authorized to access through GPUStack's Kubernetes API proxy. The cluster_apiserver_proxy handler did not perform a resource-level authorization check before forwarding requests to the selected cluster. Requests were forwarded through a worker using its Kubernetes ServiceAccount credentials. Depending on the permissions granted to that ServiceAccount, an attacker could read sensitive Kubernetes resources, create or modify workloads, or delete resources and disrupt services. Creating attacker-controlled workloads could result in code execution in the target cluster. Exploitation requires a Kubernetes-provider cluster with a reachable worker. The operations available to the attacker are limi…
### Summary SandboxShellTool's restricted modes — allowed=[...] (explicit command allowlist) and readonly=True (implicit READONLY_COMMANDS allowlist) — can both be bypassed by embedding a newline character inside the command string. The filter only inspects a single-line set of shell metacharacters, but execution runs the raw string through sh -c, where a shell treats an embedded newline exactly like a ; statement separator. An agent (or content that steers the agent, e.g. via prompt injection) can therefore run arbitrary shell commands even when the tool was configured to allow only a specific command prefix or only read-only commands. With the default LocalEnvironment() backend this is a real host subprocess (its own docstring: "Commands run via subprocess on the host, so there is n…
### Impact The callback Base64-decodes the posted XML, reads NameID and attributes, resolves or provisions the user, and mints a gpustack_session JWT — but never calls OneLogin_Saml2_Auth.process_response(), the step that verifies the signature, issuer, audience, destination, and time conditions. No credentials are required, and SAML SSO does not even need to be configured. The callback processes the payload and issues a session regardless of whether SAML is set up, so every deployment is affected, not only SAML-enabled ones. Anyone who can reach the endpoint over the network can authenticate as an arbitrary identity by posting a response that names it: - If the name matches an existing user (e.g. an administrator), the attacker receives that user's session — full account takeover, includ…
### Summary The POST /__nuxt_content/:collection/query endpoint in @nuxt/content accepts an attacker-controlled sql field from the HTTP request body and executes it against a local SQLite database after passing it through an insufficient validator (assertSafeQuery). The validator only blocks a small set of SQL command keywords and does not reject expensive SQLite built-in functions such as randomblob(), zeroblob(), hex(), or length(). An unauthenticated remote attacker can craft a single request that forces SQLite to allocate hundreds of megabytes of memory and perform CPU-intensive work, causing server-wide denial of service. This endpoint is enabled by default for every collection and requires no authentication. ### Details The vulnerability spans three source files: **R…
### Impact Like Docker Compose, compose-lint follows symlinks when it reads a project's files. Unlike Compose, compose-lint up to 0.24.0 could then put the contents of a file from *outside* the project into its output, where the author of a pull request can read it. A pull request can commit a symlink, under a name compose-lint reads, pointing at a file on the CI runner: - **The Compose file itself (0.2.0–0.24.0).** A compose.yml that is a symlink, whether the pre-commit hook passes its name or the Action or a bare run finds it. - **compose.override.yml (0.22.0–0.24.0),** which compose-lint merges automatically. - **A COMPOSE_FILE entry (0.22.0–0.24.0)** in a .env beside the Compose file. When the target is not valid YAML, the parse error quotes the line it failed on. Docker Compo…
### Impact compose-lint automatically reads a .compose-lint.yml policy file beside the Compose file. It is meant to read nothing outside the project directory, but it follows that file if it is a symlink, wherever it points. A pull request can commit .compose-lint.yml as a symlink to a file on the CI runner. If the target is not valid YAML, the error compose-lint reports quotes part of the line the parser failed on. That quote reaches the job log (standard error), JSON errors[], and the SARIF toolExecutionNotifications, which the Action uploads to Code Scanning. The run exits 2. What can be read is small. The quote is cut to about 30 characters around the error position, and the attacker cannot choose which line of the target the parser fails on. For an INI-style credentials file,…
### Impact Since 0.22.0, compose-lint fills in ${VAR} references from the .env beside the Compose file, as Compose does. The documentation says values under environment: are never resolved from a .env, "that is where secrets live". But image: values are resolved, and CL-0004 and CL-0019 quote the resolved image in their message and fix text. Some CI workflows write secrets into that .env before linting or building. In such a workflow, a pull request that changes one line to image: "${DB_PASSWORD}", or image: "nginx:${DB_PASSWORD}", gets the secret's value quoted in a finding. The finding reaches the job log, JSON output, and the SARIF uploaded to Code Scanning. GitHub masks registered secrets in the job log, but not in uploaded JSON or SARIF artifacts or in Code Scanning a…
### Impact compose-lint fix --apply converts the line numbers its fixers work with into positions in the file. The YAML parser treats a lone carriage return, U+0085, U+2028 and U+2029 as line breaks, but the conversion counted only \n. One of those characters inside a quoted value, which most editors and diff views don't show, shifted every later edit down by one line. A Compose file from a pull request can use this to make a fix delete the line after the one it meant to change. For example, fixing CL-0014 (logging: driver: none) instead removes driver: none and the following networks: [internal], moving the service off an internal-only network onto the default bridge. The result is still valid Compose, every check fix runs after editing passes, and the command reports `applie…
### Impact The GitHub Actions runner treats certain text in a step's output as commands. The legacy form, ##[command], is recognized anywhere in a line. compose-lint's text report prints service names, environment keys and lines of the Compose file, and it does not neutralize ##[. Inside the compose-lint Action, a Compose file from a pull request can therefore: - create fake error or warning annotations on the pull request (##[error], ##[warning]) - fold the rest of the log, including the real verdict, out of sight (##[group]) - blank out chosen strings for the rest of the log (##[add-mask]) GitHub has postponed removing the deprecated set-output log command, so the runner still honors it. A test run of the Action on a GitHub-hosted runner confirmed that a ::set-output lin…
### Impact compose-lint fills in ${VAR} references from the .env file next to the Compose file. It is meant to read nothing outside the project directory, and env_file:, include: and extends: paths are checked for that. The .env read is not. If .env is a symlink, compose-lint follows it wherever it points. A pull request can add a .env symlink to any file on the CI runner and a Compose file that references a variable from it. compose-lint substitutes the value and quotes it in finding messages, which go to the log and to JSON and SARIF output. The worst target is /proc/self/environ, the linter's own environment. The Compose file only needs to reference the name of the first variable in it: because that file separates variables with NUL bytes rather than newlines, the sub…
### Summary An attacker who can modify the attested workload’s code, memory-backed state, or configuration after the initial attestation — but without necessarily terminating the existing TLS connection — can cause the peer to continue trusting the connection as if the originally attested state were still running. ### Details Once attestation is successfully appraised and connection is established, there is a window of vulnerability from the establishment of connection to the termination of connection where an attacker can modify the state of the workload and platform at runtime on the TLS endpoint acting as the Attester. Workload state includes code, data, and configuration. Other examples of state changes at the workload level include cases where a new device (such as a GPU) is connecte…
## Summary An unauthenticated (**Anonymous**) client can **Write** protected Variables and **Call** privileged Methods on any Node that lacks explicit per-node permissions. This follows the inheritance model defined by OPC UA Part 3, §5.2.9, where nodes without an explicit RolePermissions attribute inherit the namespace DefaultRolePermissions. OPC 10000-3 §4.8.3 mandates a **default-deny** evaluation (Bad_UserAccessDenied when the operation bits are not set); node-opcua instead **grants all permissions**. The root cause is a combination of an authorization **fail-open** and a **disconnect** between the configuration API and the runtime enforcement path. --- ## Affected configuration This advisory covers two cases that are not equally severe: 1. No RolePermissions declared anywhere…
## Summary gopacket decodes SCTP (IP protocol 132) by walking the chunk chain through per-chunk-type decoder functions (decodeSCTPInit, decodeSCTPShutdown, decodeSCTPError, decodeSCTPSack, in layers/sctp.go). Each of these reads fixed-size header fields and runs count-driven loops **without validating the chunk's declared length against the minimums those reads require**. A single crafted SCTP segment causes a runtime panic (out-of-bounds slice read, or inverted slice from unsigned length arithmetic) on any decode path that does not install gopacket's per-packet panic recovery (gopacket.DecodeOptions.SkipDecodeRecovery: true); with the default API the same input degrades to a per-packet decode error. The defect is present in every released version through v1.7.1 and at curre…
## Summary The traversal fix for CVE-2026-33344 was implemented as HTTP middleware installed only in the chi handler chain, but the MCP service calls the same API method in process, so arbitrary YAML file read is reachable again through the MCP tool surface with a viewer-role key. Read-only, limited to .yaml/.yml targets. Confirmed at HEAD f6c039f (post v2.10.7). ## The defect The fix for CVE-2026-33344 is a reflection-based HTTP middleware (internal/frontend/.../api.go, roughly lines 553-597) that inspects a request field named FileName and rejects anything that is not a plain name. It is installed in exactly one place: the chi strict-handler chain (api.go around line 419). The MCP service does not go through that chain. internal/service/mcp/server.go calls the API method directly as an…

The flaws in the Web
An October cyberattack on refrigeration controllers at about 700 French retail sites was carried out by a cyber unit of Iran's Islamic Revolutionary Guard Corps (IRGC), the French government said yesterday. The attackers broke into controllers on the night of October 11 and changed their defrost settings to high temperatures. That caused food losses and, in at least 15 cases, fires. The unit
