What is CVE-2026-88944?
CVE-2026-88944 is a medium-severity missing authorization vulnerability in themeum Tutor LMS – eLearning and online course solution, published on 19 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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 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 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.
