CVE-2026-33714Network attack vector

Database extraction via unescaped statistics date parameters

Published Apr 14, 2026 · Updated Apr 14, 2026

SQL injection in Chamilo LMS 2.0.0-RC.2 allows remote authenticated users with admin access to extract arbitrary database data. The users_active action in public/main/inc/ajax/statistics.ajax.php inserts the date_start and date_end request values directly into a SQL query without escaping or sanitization. Administrative authentication is required, and time-based blind queries expose database contents through response timing without reported service interruption.
