The Permalinks Cascade <= 2.2 - Missing Authorization To Authenticated (Subscriber+) Plugin Settings Update
Vulnerability Description
The Permalinks Cascade plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action in the handleTPCAdminAjaxRequest function. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform unauthorized administrative actions such as enabling or disabling automatic pinging settings and modifying page exclusion settings.
