A2 Optimized WP <= 3.0.4 is vulnerable to Cross Site Request Forgery (CSRF) vulnerability

The A2 Optimized WP plugin for WordPress is vulnerable to Cross Site Request Forgery due to missing nonce validation on the 'admin_pagespeed_page' function in versions up to, and including 3.0.4. This makes it possible for unauthenticated attackers to enable data collection by the plugin developer via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
