The RapidLoad Power-Up for Autoptimize plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the clear_page_cache function in versions up to, and including, 1.7.1. This makes it possible for authenticated attackers with subscriber-level access to delete the plugin's cache.
