SCA: security update for undici (GHSA-2jfj-6hjv-fm6j)

high Tenable Self-Hosted Container Security Plugin ID 448482

Description

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

 - undici's cache interceptor does not handle the Set-Cookie response header anywhere in its cache path, so
 it neither refuses to store nor strips that header. In shared cache mode, which is the default, an
 otherwise cacheable response that carries a Set-Cookie header, for example one marked with a public and
 max-age directive, is stored and then re-served to a later caller that matches the same cache key. As a
 result one caller's cookie is disclosed to a different caller, and an untrusted server can inject cookies
 into cached responses served to all subsequent callers. This violates the requirement that a shared cache
 must not store cookies. 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-2026-84933)

Solution

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