## Description

The wpForo Forum plugin for WordPress is vulnerable to unauthorized post creation in all versions up to, and including, 3.2.2, due to the Posts::add() method skipping the forum reply ('cr'/'ocr') permission check whenever the request supplied a userid of 0 together with a name and email. This makes it possible for unauthenticated attackers, when guest posting is allowed in at least one forum, and for authenticated attackers with subscriber-level access and above, to post replies in any open topic, including topics in forums where they have no reply permission.
