Verification Bypass in jsonwebtoken

Versions 4.2.1 and earlier of jsonwebtoken are affected by a verification bypass vulnerability. This is a result of weak validation of the JWT algorithm type, occuring when an attacker is allowed to arbitrarily specify the JWT algorithm.

Recommendation

Update to version 4.2.2 or later.
