CVE-2026-93882

Impact

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 4.4.8 via the CourseMaterialTemplate::render_material_items() callback exposed on the public lp-ajax-handle (load_content_via_ajax) endpoint. The endpoint is explicitly listed in the AbstractAjax no-nonce allowlist and performs no capability check, and the render_material_items() handler decides authorization against one attacker-supplied identifier (course_id) while fetching the returned material rows via a second, independently attacker-supplied identifier (item_id) with no check that the lesson belongs to the authorized course. This makes it possible for unauthenticated attackers to read and download course-material files (uploaded and external file paths/URLs) belonging to lessons in paid or enrollment-required courses, provided any single course on the site has 'No Required Enroll' enabled and owns at least one material file.
