SCA: security update for jsrsasign (GHSA-wvqx-v3f6-w8rh)

critical Tenable Cloud Security Plugin ID 439490

Description

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

 - Versions of the package jsrsasign before 11.1.1 are vulnerable to Improper Verification of Cryptographic
 Signature via the DSA domain-parameter validation in KJUR.crypto.DSA.setPublic (and the related DSA/X509
 verification flow in src/dsa-2.0.js). An attacker can forge DSA signatures or X.509 certificates that
 X509.verifySignature() accepts by supplying malicious domain parameters such as g=1, y=1, and a fixed r=1,
 which make the verification equation true for any hash. (CVE-2026-4600)

Solution

Update the jsrsasign library and its related packages to version 11.1.1 or later.
