Advisory

Source description from Wordfence Intelligence, credited to Farid Narimanov.

The WPC Admin Columns plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.3.3. This is due to missing capability checks before returning term, user, and post meta via AJAX endpoints accessible to any authenticated user. This makes it possible for authenticated attackers, with subscriber-level access and above, to read arbitrary term, user, and post meta values belonging to any object by exploiting missing capability checks on meta retrieval AJAX handlers.
