CVE-2025-59576Network attack vector

Subscriber order-confirmation disclosure via missing capability check

Published Sep 22, 2025 · Updated Apr 28, 2026

Missing authorization in MasterStudy LMS 3.6.20 and earlier allows remote authenticated users to view other users' order confirmations. An undisclosed function returns an order confirmation without checking whether the requesting account owns the associated order. Subscriber-level access is sufficient, and the resulting exposure is limited to another customer's order-confirmation data.
