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...

@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...
