SCA: security update for fast-uri (GHSA-4c8g-83qw-93j6)

high Tenable Self-Hosted Container Security Plugin ID 445121

Description

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

 - fast-uri versions 2.3.1 through 3.1.2 and 4.0.0 fail to canonicalize Unicode (IDN) hostnames for HTTP-
 family URLs. The IDN conversion path calls a helper that does not exist on the global URL constructor,
 silently leaving the host in its original Unicode form while normalize() and equal() still return values
 that differ from a WHATWG-compatible URL parser. Applications that use fast-uri to enforce host-based
 policy (denylists, loopback filtering, redirect validation, outbound proxy routing) before passing the
 same URL to Node's URL or fetch can be bypassed when the two implementations resolve the same input to
 different hosts. Patches: upgrade to fast-uri 3.1.3 for the 3.x line or 4.0.1 for the 4.x line.
 Workarounds: enforce host policy using the same URL parser used for the actual request, or reject non-
 ASCII hosts before policy checks. (CVE-2026-13676)

Solution

Update the fast-uri library and its related packages to version 2.4.2 or later.
