Overview
Affected versions of this package are vulnerable to Insecure Encryption due to an algorithm-confusion issue (e.g., RS256 / HS256) that exists via the kid (aka Key ID) header when multiple types of keys are loaded in a key ring. This allows an attacker to forge tokens that validate under the incorrect key.
