Subscriber-level order data disclosure via ID enumeration
Published Jan 8, 2026 · Updated Jan 8, 2026
Missing authorization in Themeum Tutor LMS 3.9.3 and earlier allows remote authenticated users to read students’ order and billing data. The tutor_order_details AJAX handler passes an attacker-selected order ID to get_order_by_id() without checking the requester’s capability or ownership. Any Subscriber-level account can enumerate order IDs and disclose student names, email addresses, phone numbers, and billing addresses, without reported ability to modify orders.
