RapidLoad Power-Up for Autoptimize <= 1.7.1 - Missing Authorization in 'clear_uucss_logs'

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