[Full-disclosure] YouTube remote unsubscribe exploit

[Harry Strongburg <harry.fd@xxxxxxxx>]

A remote unsubscribe exploit has been discovered by an unknown source. 
This allows for a remote user to ubsubscribe another user's subscribers.

Example code:

You may also manually test out this bug. Send the ubsubscribe request 
numerous times and watch the count of other subscribes go down.

Again, I did not write or discover this problem. It is already well 
known, and I just hope you users here benefit from knowing about it.

Keep safe!
