CVE-2026-11483Public exploitNetwork attack vector

Unauthenticated database access via unvalidated sy parameter

Published Jun 8, 2026 · Updated Jun 8, 2026

SQL injection in SourceCodester Class and Exam Timetabling System 1.0 allows remote attackers to access its database via the sy parameter. The archive4.php endpoint passes the POST sy value directly into a MySQL query without cleaning or validation, permitting attacker-controlled SQL execution. No login is required; demonstrated blind and error-based payloads expose database contents, while database-account privileges bound modification or deletion.
