Package Change Age Confidence
js-yaml 4.1.04.1.1 age confidence

js-yaml has prototype pollution in merge (<<)

CVE-2025-64718 / GHSA-mh29-5h37-fv8m

More information

Details

Impact

In js-yaml 4.1.0, 4.0.0, and 3.14.1 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.

Patches

Problem is patched in js-yaml 4.1.1 and 3.14.2.

Workarounds

You 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).
