CVE-2025-64718 - Common Vulnerabilities and Exposures https://www.hacktheforum.com/common-vulnerabilities-and-exposures/cve-2025-64718/ Hack The Forum Discussion Board en Sat, 18 Apr 2026 18:12:39 +0000 wpForo 60 CVE-2025-64718 https://www.hacktheforum.com/common-vulnerabilities-and-exposures/cve-2025-64718/#post-19930 Tue, 18 Nov 2025 10:42:27 +0000 Description

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).
