GHSA-8j8c-7jfh-h6hx · Code Injection in js-yaml

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

Versions of `js-yaml` prior to 3.13.1 are vulnerable to Code Injection. The `load()` function may execute arbitrary code injected through a malicious YAML file. Objects that have `toString` as key, JavaScript code as value and are used as explicit mapping keys allow attackers to execute the supplied code through the `load()` function. The `safeLoad()` function is unaffected. An example payload is `{ toString: !<tag:yaml.org,2002:js/function> 'function (){return Date.now()}' } : 1` which returns the object { "1553107949161": 1 } ## Recommendation Upgrade to version 3.13.1.
