W3 Total Cache <= 0.9.4 - Cross-Site Request Forgery leading to Stored Cross-Site Scripting

The W3 Total Cache plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 0.9.4. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page via forged request granted they can trick a site administrator into performing an action such as clicking on a link.
