Kerentanan Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') pada nodeca js-yaml. Skor CVSS 3.1 5.3 (Medium) menurut github.com.

Deskripsi (NVD)

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).
