Echo: fast-uri: security update to 2.4.5

high Tenable Cloud Security Plugin ID 459274

Description

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

 - fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input
 carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is
 returned with its host verbatim and no error set. As a result fast-uri's own entry points disagree with
 each other: parse, resolve, normalize, and equal can yield different hosts for the same input depending
 only on whether a scheme is written out, and equal can return opposite verdicts for the same pair of
 hosts. An application that extracts a host with fast-uri to check it against a policy list and then
 resolves the same reference can make its decision on one host while the destination is another, enabling
 host confusion and policy bypass. The affected versions are 2.4.2 up to but not including 2.4.5, 3.1.3 up
 to but not including 3.1.6, and 4.0.1 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6,
 and 4.1.3, which canonicalize the host consistently across the resolve path. Users should upgrade to a
 patched version. (CVE-2026-75931)

Solution

Update the fast-uri library and its related packages to version 2.4.5 or later.
