Advisory
Source description from Wordfence Intelligence, credited to Duy Tran.
The TaxoPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.50.0. This is due to missing authorization check on a user-supplied post ID passed to get_post() in the AI preview AJAX handler, allowing any authenticated user to retrieve post data regardless of post status or ownership. This makes it possible for authenticated attackers, with contributor-level access and above, to read the content of private or draft posts belonging to other users by supplying an arbitrary post ID.
