Input validation vulnerability in Fast WP Speed 1.0.0

The Fast WP Speed plugin for WordPress is vulnerable to a type of attack called Reflected Cross-Site Scripting. This is a security issue in versions up to, and including, 1.0.0 of the plugin. It occurs because the plugin does not properly sanitize and escape user input, which makes it possible for an unauthenticated attacker to inject malicious web scripts into pages. Someone can do this if they can convince a user to take an action, like clicking on a link.
