Official description

The Custom Post Type UI plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.18.0. This is due to the plugin not verifying that a user has the required capability to perform actions in the "cptui_process_post_type" function. This makes it possible for authenticated attackers, with subscriber level access and above, to add, edit, or delete custom post types in limited situations.
