SCA: security update for undici (GHSA-pmjh-fq2x-6v4x)

medium Tenable Cloud Security Plugin ID 448488

Description

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

 - undici's retry handler can leave an already-exposed response body pending forever. When a server returns a
 successful response that declares a Content-Length, sends only part of the body, and closes the
 connection, the retry handler retries the request. If the retry returns a non-retryable status such as
 400, the handler forwards that new response downstream and replaces its internal response stream, but the
 original response body that the application still holds is never ended or destroyed. As a result calls
 that read that body never settle, and the configured body timeout does not fire because its timer is tied
 to the connection parser rather than the orphaned body. An attacker-controlled server can trigger this
 with two short responses without keeping a connection open, and repeated requests accumulate pending
 promises and streams that can exhaust application concurrency or memory. This affects undici versions from
 7.11.0 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-2026-18149)

Solution

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