SCA: security update for undici (GHSA-3xpg-4rpp-hhhm)

medium Tenable Self-Hosted Container Security Plugin ID 448492

Description

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

- undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding
header. While the number of content-encoding layers is capped, the total decompressed output size is
unbounded and there is no configuration option to limit it. A malicious or faulty upstream can therefore
return a small compressed payload, a compression bomb, that expands to hundreds of megabytes or more in
client memory, an asymmetric resource consumption that can exhaust memory and crash the process. This
affects undici versions from 7.15.0 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-2026-84890)

Solution

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