Advisory

Source description from Wordfence Intelligence, credited to Kyle Sanchez.

The WP Post Author plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the awpa_pro_api_post_rating_review() function in all versions up to, and including, 3.7.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to leave reviews on private posts.
