SCA: security update for undici (GHSA-hm92-r4w5-c3mj)

high Tenable Self-Hosted Container Security Plugin ID 443608

Description

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

 - Impact: When using Socks5ProxyAgent, undici reuses a single connection pool across different origins
 without verifying that the pool's origin matches the requested origin. All requests are dispatched through
 the pool connected to the first origin, regardless of the intended destination. This causes cross-origin
 request routing: credentials and request data intended for origin B are sent to origin A, responses from
 the wrong origin are trusted, and HTTPS requests may be silently downgraded to HTTP. Impacted users are
 applications that use Socks5ProxyAgent (directly or via setGlobalDispatcher) and make requests to more
 than one origin. This was introduced in undici 7.23.0 via PR #4385 and affects all versions through 8.1.0.
 Patches: Upgrade to undici v7.26.0 or v8.2.0. Workarounds: Use a separate Socks5ProxyAgent instance per
 origin, or avoid using Socks5ProxyAgent with multiple origins. (CVE-2026-6734)

Solution

Update the undici library and its related packages to version 7.28.0 or later.
