Technical details
A client-side enforcement vulnerability (CWE-602) exists in Frappe LMS versions prior to 2.46.0. The application relies on the client-side browser to calculate and transmit quiz scores rather than performing the calculation on the server. An authenticated student can use browser developer tools to intercept and modify the score value in the submission request. This allows for the manipulation of personal grade data, though it does not provide a path for privilege escalation or unauthorized access to other users' data. The issue is resolved in version 2.46.0 by implementing server-side score validation.
