Advisory

Source description from Wordfence Intelligence, credited to Farid Narimanov.

The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 5.2.5. This is due to missing authorization checks on AJAX handlers for import job actions, allowing any authenticated user to act on posts they do not own. This makes it possible for authenticated attackers, with author-level access and above, to manipulate or delete import jobs belonging to other users, including triggering runs, purging data, and clearing error logs.
