CVE-2026-85014

undici , the Node.js HTTP client library, contains a Denial of Service vulnerability in its experimental WebSocketStream client. When a remote peer closes the TCP connection without a proper WebSocket close handshake, the internal socket-close handler unconditionally calls abort on a locked writa...

undici: undici: Denial of Service via WebSocketStream unclean close

A flaw was found in undici's experimental WebSocketStream client. A remote attacker, operating as an untrusted server, can trigger a Denial of Service DoS by closing the TCP connection without a proper WebSocket close handshake. This action causes an unhandled error in the client, leading to the...
