Found in base branch: main

Vulnerability Details

js-yaml is a JavaScript YAML parser and dumper. In js-yaml 4.1.0 and below, 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. 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).
