Description
A flaw was found in undici. A remote attacker can exploit this vulnerability by sending a specially crafted compressed frame, known as a "decompression bomb," during permessage-deflate decompression. The undici WebSocket client does not properly limit the size of decompressed data, leading to unbounded memory consumption. This can cause the Node.js process to exhaust available memory, resulting in a denial of service (DoS) where the process crashes or becomes unresponsive.
