  "details" : [ "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 promise, but per the WHATWG Streams standard aborting a locked writable returns a promise that rejects with a TypeError. Because the application holds a writer on that writable, which is the only way to write, the rejection is never observed and Node's default unhandled-rejection behavior terminates the process. An untrusted server can therefore crash a client with a single abrupt disconnect, with no authentication and no application mistake. This affects undici versions from 7.0.0 up to 7.29.1 and from 8.0.0 up to 8.10.2. Users should upgrade to undici 7.29.1 or 8.10.2.", "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 termination of the entire Node.js process." ],
  "statement" : "This Moderate impact flaw in the `undici` library's experimental `WebSocketStream` client can lead to a denial of service. An untrusted remote server can crash a vulnerable Node.js client application by abruptly closing a TCP connection without a WebSocket handshake. This affects the availability of applications utilizing `undici` in Red Hat products.",
