 "title": "wpForo Forum <= 3.2.2 - Authenticated (Subscriber+) Missing Authorization to Guest Post Modification",
 "description": "The wpForo Forum plugin for WordPress is vulnerable to unauthorized modification of data via the post_edit action in all versions up to, and including, 3.2.2. This is because the Posts::edit() method treated any edit of a guest-authored post (userid 0) as guest posting whenever the request contained name and email fields, and then skipped the edit permission check, including for logged-in users. This makes it possible for authenticated attackers with subscriber-level access and above to modify the content of any guest-authored forum post.",
