## Description

The Superb Addons plugin for WordPress is vulnerable to unauthorized page creation and deletion via the 'elementor-tour' and 'cleanup-elementor-tour-page' actions of the tutorial REST route in all versions up to, and including, 4.2.3. This is due to the route checking only the edit_posts capability, TourController::GetElementorTourURL() creating a page without checking edit_pages, and TourController::CleanUpTourPage() permanently deleting the stored tutorial page without checking delete_post or whether the page is still a draft. This makes it possible for authenticated attackers with contributor-level access and above to create draft tutorial pages, obtain the tutorial nonce, and permanently delete the stored tutorial page, including one created by another user.
