CVE-2026-8279 PUBLISHED

The Masteriyo LMS plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the 'delete_item_permissions_check' function in the CourseProgressItemsController in all versions up to, and including, 2.2.0. This makes it possible for unauthenticated attackers to delete arbitrary course progress records belonging to any student.
