Description
The Widgets for Reviews & Recommendations plugin for WordPress is vulnerable to uncontrolled resource consumption via the online visitor counter endpoint in all versions up to, and including, 14.3, due to the getOnlineUsers() function creating a new database option for every distinct 'p' parameter value and a new transient for every IP address and user agent, with no limit on how many are created. The only check is a nonce that is printed on every front-end page. This makes it possible for unauthenticated attackers to fill the wp_options table with any number of rows, which degrades site performance.
