No affected components available
Versions 2.0.4 and earlier of js-yaml are affected by a code execution vulnerability in the YAML deserializer.
Proof of Concept
const yaml = require('js-yaml');
const x = `test: !!js/function >
function f() {
console.log(1);
}();`
yaml.load(x);
Recommendation
Update js-yaml to version 2.0.5 or later, and ensure that all instances where the .load() method is called are updated to use .safeLoad() instead.
