Cross site request forgery (csrf)

The RapidLoad Power-Up for Autoptimize plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.7.1. This is due to missing or incorrect nonce validation on the attach_rule function. This makes it possible for unauthenticated attackers to modify the plugin’s cache via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
