SCA: security update for js-yaml (GHSA-mh29-5h37-fv8m)

medium Tenable Self-Hosted Container Security Plugin ID 436056

Description

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

 - js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it's possible for an
 attacker to modify the prototype of the result of a parsed yaml document via prototype pollution
 (`__proto__`). All users who parse untrusted yaml documents may be impacted. The problem is patched in js-
 yaml 4.1.1 and 3.14.2. Users can protect against this kind of attack on the server by using `node
 --disable-proto=delete` or `deno` (in Deno, pollution protection is on by default). (CVE-2025-64718)
