undici: undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression

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...
