Unauthenticated course disclosure via missing publication check

Published Feb 20, 2026 · Updated Feb 20, 2026

Missing authorization in Frappe Learning 2.44.0 and earlier allows remote attackers to read unpublished course details through API endpoints. Course-detail API endpoints returned records without first checking the course's published state and restricting unpublished records to administrators or enrolled students. No account is required, and the exposed data is limited to unpublished course details; no modification or service interruption is reported.
