The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.8.

This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently delete arbitrary WordPress posts — including pages, courses, quizzes, and WooCommerce products — via wp_delete_post( $id, true ). The exploit chain requires the attacker to first trigger the profile-photo upload flow to obtain an authored wp_posts attachment row, then create a Tutor topic reparented to that attachment, before invoking the lesson deletion handler against any target post ID.
