Input validation vulnerability in W3 Total Cache 0.9.4

The W3 Total Cache plugin for WordPress is vulnerable to a security risk called Cross-Site Request Forgery. This security risk affects versions of the plugin up to, and including, 0.9.4. This means attackers who are not authenticated (not allowed on the website) could inject web scripts into pages that would be executed when a user visits them, as long as they can get the website administrator to do something like click a link.
