SCA: security update for undici (GHSA-3wwx-pv8p-q78v)

medium Tenable Cloud Security Plugin ID 448450

Description

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

- undici bundles a WebSocket client whose permessage-deflate size-limit cleanup removes all listeners from
the internal zlib inflate stream, including its error listener, while that stream can still emit. When a
remote peer sends a compressed payload that crosses the built-in 128 MiB decompressed-payload limit and
then contains a malformed DEFLATE byte, the inflate stream emits a data error with no listener attached,
which Node.js treats as a fatal unhandled error and terminates the entire process. Exploitation is remote
and unauthenticated, requires no application mistake, and is asymmetric, since roughly 130 KB on the wire
expands past the limit and crashes the process, and reconnecting can repeat the crash. This affects undici
versions from 6.25.0 up to 6.28.1, from 7.28.0 up to 7.29.1, and from 8.1.0 up to 8.10.2. Users should
upgrade to undici 6.28.1, 7.29.1, or 8.10.2. (CVE-2026-85024)

Solution

Update the undici library and its related packages to version 6.28.1 or later.
