LearnPress <= 4.4.8 — Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'item_id' Parameter

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under LearnPress – WordPress LMS Plugin for Create and Sell Online Courses.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 4.4.9, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch LearnPress – WordPress LMS Plugin for Create and Sell Online Courses to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Khoa Dang.

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.
