SCA: security update for undici (GHSA-8436-99hf-9mmv)

medium Tenable Cloud Security Plugin ID 448471

Description

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

 - undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching
 is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as
 POST, PUT, or DELETE is never placed in the skip list and instead falls through to the full cache-read
 path. The response-storage gate also lacked a method check, so a response to an unsafe request that is
 heuristically cacheable or carries an explicit Cache-Control directive is stored and later replayed from
 cache. Because response headers from a remote origin are untrusted, an origin can answer once with a
 cacheable status and then have the client's own subsequent state-changing requests to that path served
 from the stale cache entry without ever reaching the origin, an integrity failure that occurs under the
 interceptor's default configuration. 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-2026-85008)

Solution

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