An unauthenticated POST with username ' OR '1'='1' -- - returns success and a session that loads the admin dashboard, which controls exams, questions, examinees, results, and feedback. Admin passwords are stored in plaintext. CVSS 3.1 score 9.8 Critical, vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. Discovered by Santhosh Kumar, TraceX Labs.
