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...
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...

CVE-2026-19481
Summary: CVE-2026-19481 affects the multipart-form data parser in the @fastify/busboy package (versions 1.0.0–3.2.0). An attacker can submit multipart data with a part header named after a prototype-inherited property (e.g., proto , constructor), causing the header parser (which stores headers in...
