| CVE-2025-64718 | — | >= 4.0.0, < 4.1.1 | 4.1.1 | Nov 13, 2025 | 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. T | ||
