CVE-2026-97883Public exploitNetwork attack vector

Database read and alteration via unescaped gid

Published Sep 25, 2026 · Updated Sep 25, 2026

SQL injection in Cloud Classroom allows remote attackers to read or alter database data through a crafted gid parameter. updatequery.php places gid directly into an unquoted SELECT expression and later reuses it in an UPDATE statement without binding or validation. The session guard only sends a redirect and does not stop execution, so no authenticated session is required and database access is limited by the application's database account.
