SCA: security update for undici (GHSA-v3r7-h72x-cjcm)

medium Tenable Cloud Security Plugin ID 445601

Description

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

 - undici's setCookie function does not fully sanitize cookie attributes. In undici before 6.28.0, from 7.0.0
 up to before 7.29.0, and from 8.0.0 up to before 8.9.0, a domain value is not checked for semicolons and
 entries in the unparsed array are not sanitized, so attacker-influenced input can inject additional cookie
 attributes. For example, a domain value containing a semicolon can append attributes such as SameSite, and
 an unparsed entry can inject attributes such as HttpOnly, without the caller setting them. Applications
 that pass user-controlled input to these fields, such as multi-tenant or reverse-proxy servers that scope
 session cookies to a tenant-supplied domain, can have SameSite CSRF protections bypassed, or the Secure,
 HttpOnly, and SameSite attributes forced, stripped, or overridden. The issue is fixed in undici 6.28.0,
 7.29.0, and 8.9.0. (CVE-2026-16729)

Solution

Update the undici library and its related packages to version 6.28.0 or later.
