kk Star Ratings < 5.4.6 - Rating Manipulation via Race Condition

The kk Star Ratings plugin before version 5.4.6 in WordPress allows attackers to manipulate ratings by exploiting a race condition. By intercepting the rating submission request using tools like Burp and Turbo Intruder, an attacker can send multiple requests simultaneously to the server, resulting in the manipulation of star ratings.

Mitigation:

Update to version 5.4.6 or later of the kk Star Ratings plugin to prevent exploitation of this vulnerability. Additionally, monitor and rate-limit incoming requests to detect and prevent suspicious rating activities.
