Advisory

Source description from Wordfence Intelligence.

The bbPress Move Topics plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 1.1.4 via deserialization of untrusted input via the 'aforums_move_topics_page()' function where it passes the decoded 'allforums' value through the 'unserialize()' function. This allows authenticated attackers to inject a PHP Object.
