The Fastcache by Host.it plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.7.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to add or remove the plugin's page-cache rewrite rules in the site's root .htaccess file.
