CVE-2026-76999Public exploitNetwork attack vector

Unauthorized grade changes via student_id tampering

Published Aug 20, 2026 · Updated Aug 20, 2026

Improper authorization in CET Automated Grading System with AI Predictive Analytics 1.0 lets authenticated users alter grades via student_id tampering. Public sources name the /index.php add_grade handler and the student_id parameter as the locus, but they do not disclose the exact authorization check that is missing or bypassed. Reachability is remote over the web application and requires an authenticated session; the stated impact is unauthorized modification of student-linked grading data, with no public evidence of broader administrator takeover.
