CVE-2026-85014 undici vulnerable to Denial of Service via WebSocketStream unclean close

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...

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...

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,...

CVE-2026-12151: Uncontrolled Resource Consumption

Impact: The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size...
