Signature Verification Bypass in jwt-simple

Versions of jwt-simple prior to 0.5.3 are vulnerable to Signature Verification Bypass. If no algorithm is specified in the decode function, the packages uses the algorithm in the JWT to decode tokens. This allows an attacker to create a HS256 symmetric algorithm JWT with the server's public key a...
