Technical details
The ratings plugin AJAX handler (ratings.ajax.php) accepts POST requests to modify ratings without validating CSRF tokens, relying only on user authentication. An attacker can craft a malicious webpage that auto-submits requests to the ratings endpoint, and when visited by an authenticated user, the requests execute with that user's privileges. The vulnerability requires the victim to be logged in and to visit an attacker-controlled page, but no user interaction is needed once the page loads.
