Input validation vulnerability in Asset CleanUp: Page Speed Booster 1.3.6.7

The Asset CleanUp: Page Speed Booster plugin for WordPress is vulnerable to a security issue called Reflected Cross-Site Scripting. This security issue allows unauthenticated attackers to inject malicious code into the administrative pages of websites running this plugin. This malicious code will run if administrators click on a link that has been created by the attackers. This vulnerability affects versions of the plugin up to and including 1.3.6.6 due to the lack of proper input sanitation and output escaping.
