SCA: security update for jsrsasign (GHSA-w8q8-93cx-6h7r)

critical Tenable Cloud Security Plugin ID 439444

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 Missing Cryptographic Step via the
 KJUR.crypto.DSA.signWithMessageHash process in the DSA signing implementation. An attacker can recover the
 private key by forcing r or s to be zero, so the library emits an invalid signature without retrying, and
 then solves for x from the resulting signature. (CVE-2026-4601)

Solution

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