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 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...

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...

Name of the Vulnerable Software and Affected Versions xmldom versions 0.9.0-beta.9 through 0.9.10 Description The processing-instruction production in lib/grammar.js allows a greedy S+ separator and lazy Char? data group to repeatedly repartition a long whitespace tail when the closing ? is...

SUSE CVE-2026-69152

The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to 1.1.18, 2.1.4, 3.0.6, and 5.0.9, expand does not apply maxLength while constructing comma-alternative intermediate arrays or padded sequences, allowing attacker-controlled input to exhaust memo...
