CVE-2025-50190Network attack vector

Database disclosure via unescaped OpenID association handle

Published Mar 2, 2026 · Updated Mar 2, 2026

SQL injection in Chamilo LMS before 1.11.30 allows remote attackers to read database data or interrupt service through an OpenID request. In main/auth/openid/login.php, openid_verify_assertion() interpolates the unescaped openid.assoc_handle response value into a quoted SQL WHERE clause. No account or user interaction is required, but the OpenID module must be enabled; it is disabled by default.
