Advisory
Source description from Wordfence Intelligence, credited to Muni Nitish Kumar Yaddala.
The BuddyForms plugin for WordPress is vulnerable to Improper Authorization in versions 2.8.8 through 2.10.0. This is due to missing check for an empty current user ID before comparing post_author to the requesting user, causing all unauthenticated users to share user ID 0 and match any guest-uploaded attachment. This makes it possible for unauthenticated attackers to permanently delete media attachments uploaded by other unauthenticated visitors by exploiting the shared guest user ID of 0. A form with public (guest) file upload must be active on the site.
