Details

Deserialization Code Execution in js-yaml 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.
