SCA: security update for undici (GHSA-rx4f-c7p8-82vq)

high Tenable Self-Hosted Container Security Plugin ID 448463

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-85014)

Solution

Update the undici library and its related packages to version 7.29.1 or later.
