SCA: security update for undici (GHSA-35p6-xmwp-9g52)

low Tenable Cloud Security Plugin ID 443603

Description

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

 - Impact: Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets.
 An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket
 after a request completes. When the client dispatches the next request on that socket, it associates the
 injected response with the new request, causing responses to be delivered to the wrong requests. This
 requires an attacker-controlled or compromised upstream HTTP/1.1 server and keep-alive connection reuse.
 Patches: Upgrade to undici v6.26.0, v7.28.0 or v8.5.0. Workarounds: Disable keep-alive connection reuse by
 setting keepAliveTimeout: 0 on the Client or Pool. (CVE-2026-6733)

Solution

Update the undici library and its related packages to version 6.27.0 or later.
