Today i was sitting in my ts server and a user joined and kicked me, as far as i can see they didn't have any admin privileges. I proceeded to check the team speak privileges and everything was set correctly. How is this possible for a random user to join and kick a high admin?

I also have had random users join my ts and were able to add themselves to every group in my team speak server. Is there some kind of hack for team speak 3 that i am not aware of?
