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...
