Description

A flaw was found in undici. A remote attacker could exploit this vulnerability by sending a specially crafted WebSocket frame with an extremely large 64-bit length. This causes undici's ByteParser to overflow its internal calculations, leading to an invalid state and a fatal TypeError. The primary consequence is a Denial of Service (DoS), which terminates the process.
