The wpForo Forum plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 3.2.2 via the data[secondarygroupids] parameter of the wpforoactionprofileupdate POST handler. This is due to a type-confusion flaw in the secondarygroupids authorization guard within the Members::update() function in classes/Members.php, where casting a scalar CSV string (e.g. "0,1") with (array) before arraymap('intval', …) and arrayfilter() produces an empty array — causing the guard's outer conditional, and the else-branch that would otherwise strip the field from the update, to be bypassed entirely — while encode()/decode() downstream correctly explodes the original CSV and persists the attacker-supplied group IDs to wpwpforoprofiles.secondarygroupids. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their forum privileges to wpForo Administrator by injecting the privileged Admin group ID, granting access to the Forum Accesses editor and the ability to rewrite forum-wide capability policies for all members and edit arbitrary content owned by other users. Exploitation requires the attacker to have at least 3…
