Advisory
Source description from Wordfence Intelligence, credited to Mustafa Ahmed.
The BuddyPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 14.4.0. This is due to missing validation on the user_id request parameter in the messages REST endpoint, allowing non-moderator users to specify another user's ID to pass thread access checks. This makes it possible for authenticated attackers, with subscriber-level access and above, to read private message threads belonging to other users by supplying an arbitrary user_id parameter in REST API requests.
