Advisory

Source description from Wordfence Intelligence, credited to Jesse McNeil.

The wpForo Forum plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 2.2.3. This is due to incorrect assignment of user permissions during registration. This makes it possible for unauthenticated attackers to elevate their privileges to that of an administrator.
