WPS Cleaner <= 1.4.4 - Missing Authorization Checks

The WPS Cleaner plugin for WordPress is vulnerable to authorization bypass in versions up to, and including, 1.4.4. This is due to missing capability and nonce checks on 7 different functions found in the '/classes/plugin.php' file. This makes it possible for authenticated attackers with minimal permissions, such as a subscriber, to perform a variety of actions such as deleting arbitrary files, creating zip archives, deleting zip archives, and deleting alerts among some additional actions.
