CVE-2026-74866

A flaw was found in @fastify/busboy, a Node.js multipart form-data parser. The parser incorrectly handles lone carriage return or line feed characters in multipart part headers, treating them as part of the filename or field name rather than as line breaks. A remote attacker could exploit this by...

SUSE CVE-2026-74866

@fastify/busboy is a multipart form-data parser for Node.js. Its multipart part-header parser splits header lines only on the two-byte carriage-return line-feed sequence, so a lone carriage return or line feed embedded in a part header is not treated as a line break and is carried verbatim into t...

CVE-2026-19484

A flaw was found in @fastify/busboy, a multipart form-data parser. A remote, unauthenticated attacker can exploit this by sending a specially crafted multipart request with an oversized boundary. This can cause the Node.js event loop to stall, leading to a CPU-bound loop that consumes significant...

CVE-2026-19481

A flaw was found in @fastify/busboy, a multipart form-data parser. A remote attacker can exploit this vulnerability by sending specially crafted multipart form-data headers. This can cause a TypeError in the parser, leading to the termination of the Node.js process and resulting in an...

SUSE CVE-2026-19481

@fastify/busboy is a multipart form-data parser. In versions 1.0.0 through 3.2.0, an attacker who can submit multipart form-data can crash the parser by sending a part header whose name is a prototype-inherited property such as proto or constructor. The internal header parser stores headers in a...

SUSE 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-2026-18549

@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...
