DESCRIPTION: NBBN has discovered a vulnerability in phpBB, which can be exploited by malicious people to conduct cross-site request forgery attacks. The vulnerability is confirmed in version 2.0.22. Other versions may also be affected.

The vulnerability is caused due to the application allowing users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to delete all of a user's private messages.
