SCA: security update for undici (GHSA-4cwx-7wf7-3272)

high Tenable Cloud Security Plugin ID 445598

Description

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

 - undici's cache interceptor mishandles malformed Cache-Control private directives. In undici 7.0.0 up to
 before 7.29.0 and 8.0.0 up to before 8.9.0, a response carrying a degenerate qualified private directive,
 such as private set to an empty value, can be stored in the default shared cache and later served to a
 different caller with the same cache key, disclosing private response bodies and headers including Set-
 Cookie. Separately, a Cache-Control header that combines an unqualified private directive with a qualified
 one triggers an uncaught TypeError in the cache-control parser, which rejects the request and, depending
 on the consumer's error handling, can terminate the process. Both issues affect applications using the
 cache interceptor in shared mode, including the default configuration. The issues are fixed in undici
 7.29.0 and 8.9.0. (CVE-2026-13697)

Solution

Update the undici library and its related packages to version 7.29.0 or later.
