CVE-2026-40455

Database disclosure via unvalidated tariff tags

Published Jun 18, 2026 · Updated Jun 18, 2026

SQL injection in LMS before commit 4cb30a7 allows remote authenticated users to read sensitive database data through crafted tariff tags. The tarifflist.php module passes POST tg[] array values through implode() into an SQL query without first restricting them to integers. Access to the authenticated tariff-list workflow is required, and error-based injection exposes database contents.
