In this video, I'll talk about JWT (JSON Web Token) confusion attack. The confusion between implementing two types of algorithms (symmetric key and asymmetric key) is the root cause of the confusion attack. Using this, an attacker will be able to spoof his JWT token and give himself superuser/administrator permissions on the server.
