Description

The Vuukle Comments Reactions Share Bar Revenue plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 3.4.31. This is due to missing or incorrect nonce validation in the /admin/partials/free-comments-for-wordpress-vuukle-admin-display.php file.
