  "title": "node-js-yaml: js-yaml is a JavaScript YAML parser and dumper",
  "description": "js-yaml is a JavaScript YAML parser and dumper. In js-yaml before 4.1.1 and 3.14.2, it\u0027s possible for an attacker to modify the prototype of the result of a parsed yaml document via prototype pollution (\u0060__proto__\u0060). 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 \u0060node --disable-proto=delete\u0060 or \u0060deno\u0060 (in Deno, pollution protection is on by default).",
