Sensitive database disclosure via unchecked SQL execution
Published Jul 27, 2026 · Updated Jul 27, 2026
SQL injection in Dede CMS 5.7.118 allows remote attackers to read sensitive database data through sys_sql_query.php's sqlquery parameter. The component sends the attacker-controlled value to the database after its safeCheck validation is disabled, and error responses reveal query results. No authentication or user interaction is required, and the demonstrated consequence is disclosure rather than data modification or service interruption.
