Description
The W3 Total Cache plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 2.8.1. This makes it possible for unauthenticated attackers to deactivate the plugin as well as activate and deactivate plugin extensions.
