CVE-2026-40455 is an authenticated SQL injection vulnerability in LMS (LAN Management System) affecting versions before commit 4cb30a7. The flaw is located in the tarifflist.php module, where the application insufficiently sanitizes the POST tg[] parameter and directly concatenates user-controlled array values into an SQL query via implode(). This unsafe query construction enables error-based SQL injection against the backend database and allows an authenticated attacker to manipulate SQL execution and extract sensitive database information.
