Description
Frappe Learning Management System (LMS) is a learning system that helps users structure their content. Prior to 2.46.0, a vulnerability has been identified in Frappe Learning where quiz scores can be modified by students before submission. The application currently relies on client-side calculated scores, which can be altered using browser developer tools prior to sending the submission request. While this does not allow modification of other users’ data or privilege escalation, it compromises the integrity of quiz results and undermines academic reliability. This issue affects data integrity but does not expose confidential information or allow unauthorized access to other accounts. This vulnerability is fixed in 2.46.0.
