CVE-2026-18549 @fastify/multipart vulnerable to Denial of Service via aborted upload after fileSize limit

@fastify/multipart is a multipart form-data parser for Fastify. In versions from 5.3.0 up to but not including 10.1.1, when the busboy fileSize limit truncates a file part, the plugin clears its internal current-file reference while the underlying stream is still open. If the client then aborts t...

CVE-2026-73643

A flaw was found in js-yaml, a JavaScript YAML parser. A remote attacker could exploit this vulnerability by providing specially crafted YAML input containing nested flow collections. This can lead to exponential parsing time when the application processes untrusted input, consuming excessive CPU...

CVE-2026-73569 fast-xml-parser: Repeated DOCTYPE declarations reset entity expansion limits

fast-xml-parser allows users to process XML from JS object without C/C++ based libraries or callbacks. From 5.9.3 until 5.10.1, src/xmlparser/OrderedObjParser.js processes multiple DOCTYPE declarations within a single XML document and passes each declaration's entities through addInputEntities...

CVE-2026-19484

@fastify/busboy is a multipart form-data parser. In versions 3.1.0 through 3.2.0, a remote unauthenticated attacker can stall the Node.js event loop by sending a multipart request whose boundary is crafted to a specific length. The vendored streaming search stores its skip table in a fixed 256...

CVE-2026-19484

@fastify/busboy versions 3.1.0–3.2.0 are vulnerable to a Denial of Service via crafted multipart boundaries. The root cause is a fixed 256-entry skip table in the vendored streaming search; a boundary of exactly 252 bytes makes the search needle 256 bytes, truncating the skip distance to zero and...

CVE-2026-19484 @fastify/busboy vulnerable to Denial of Service via oversized multipart boundary

@fastify/busboy is a multipart form-data parser. In versions 3.1.0 through 3.2.0, a remote unauthenticated attacker can stall the Node.js event loop by sending a multipart request whose boundary is crafted to a specific length. The vendored streaming search stores its skip table in a fixed 256...

brace-expansion: Brace-expansion: Denial of Service due to exponential-time complexity

A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the expand function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-lo...

brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

A flaw was found in the brace-expansion library. The expand function does not apply maxLength when constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memory or block the event loop, resulting in a denial of service. This issue is...

CVE-2026-70493

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 until 0.11.0, the built-in knowledge search path in backend/openwebui/tools/knowledgefs.py and backend/openwebui/tools/builtin.py let a chat participant choose a pattern used to grep knowledge files...

CVE-2026-67199 Perspective 5.0.0 DoS via Loop Expression Evaluation

Perspective 5.0.0 contains a denial of service vulnerability that allows remote attackers to block the server event loop indefinitely by submitting a crafted expression containing unbounded for or while loop constructs in a TableMakeViewReq message. Attackers can embed an arbitrarily large...

GHSA-RGW5-RVV9-X895 brace-expansion: DoS via unbounded intermediate arrays, bypassing the CVE-2026-14257 mitigation

Summary The maxLength mitigation added in 5.0.8 for GHSA-mh99-v99m-4gvg / CVE-2026-14257 is incomplete. It bounds the accumulator where results are combined, but not the intermediate arrays that feed it. A 25 KB input still crashes the Node process with an uncatchable out-of-memory error, so...
