undici vulnerable to Denial of Service via WebSocketStream unclean close

Impact undici's WebSocketStream crashes the client process when a WebSocket connection is closed abruptly without a close handshake. On such an unclean close, the internal socket-close handler calls abort on the writable stream even when the application holds a writer lock. Per the WHATWG Streams...

undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames

A flaw was found in undici. A malicious WebSocket server can exploit this by streaming numerous small or empty continuation frames. This can bypass per-frame and cumulative-size validation, leading to unbounded memory growth in the client process. The primary consequence is memory exhaustion,...

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...

SUSE CVE-2026-85014

undici's experimental WebSocketStream client crashes the whole Node.js process when a remote peer closes the TCP connection without a WebSocket close handshake. On an unclean close the internal socket-close handler calls abort on the writable stream unconditionally and discards the returned...
