"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2025-1123 advisory.

    A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been
    rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation
    leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of
    an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the
    public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue.
    The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the
    affected component. (CVE-2025-5889)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
