UBUNTU-CVE-2026-19534

undici's WebSocket client crashes the whole Node.js process during the opening handshake when a server responds with a subprotocol that the client never requested. A default WebSocket connection sends no subprotocol, but if the server's 101 response includes a Sec-WebSocket-Protocol header, undic...

CVE-2026-19534

A flaw was found in undici. A remote attacker can exploit this vulnerability by responding with an unrequested WebSocket subprotocol during the opening handshake. This causes the undici WebSocket client to crash the entire Node.js process, leading to a denial of service DoS. Mitigation Mitigation...

DEBIAN-CVE-2026-85152

undici 8.10.0 omits the destination origin from the cache and request-deduplication keys when the cache or deduplicate interceptor is composed directly onto a Client or Pool. Because the internal cache key falls back to an empty origin string, a cacheable or in-flight response from one upstream...

DEBIAN-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...

DEBIAN-CVE-2026-84947

undici's dump interceptor reads and discards a response body up to a configurable maximum size. When a response declares a Content-Length that exceeds the maximum, the interceptor aborts cleanly, but when a response has no Content-Length and is chunked, the interceptor instead signals completion...

CVE-2026-19534

CVE-2026-19534 affects undici , the Node.js HTTP client library. During the WebSocket opening handshake, if a server's 101 response includes a Sec-WebSocket-Protocol header that the client never requested, undici dereferences a null value while checking it against the requested subprotocol list, ...

CVE-2026-85014

CVE-2026-85014 affects undici's experimental WebSocketStream client in Node.js. When a remote peer closes the TCP connection without a proper WebSocket close handshake, the internal socket-close handler calls abort on the locked writable stream and discards the returned promise. Per the WHATWG St...
