SCA: security update for undici (GHSA-4cwx-7wf7-3272)
critical Tenable Self-Hosted Container 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.See Also
