Authenticated student users can manipulate the invoice ID parameter in the URL to access other students’ invoices without authorization. This results in unauthorized disclosure of personal and financial information.

1. Naviagte to: http://127.0.0.1:8000/login and Log in as a student the given credentials are: Email: [email protected] | Password: password
2. Navigate to Fees and click on View Fee Invoice.
3. Click on Action and click View, and observe the URL in the browser’s address bar: http://127.0.0.1:8000/dashboard/fees/fee-invoices/46
4. Modify the invoice ID in the URL (e.g., change 46 to 45): http://127.0.0.1:8000/dashboard/fees/fee-invoices/45
5. The application displays the invoice of Student XYZ even Student ABC can print Student XYZ invoice.
