SQL Injection in Cubecart V6
CVE-2026-54646
CubeCart is an ecommerce software solution. Prior to 6.7.5, admin/sources/maintenance.index.inc.php places administrator-controlled tablename values into ALTER TABLE, CHECK TABLE, and ANALYZE TABLE statements without validating the identifiers or escaping embedded backticks. An authenticated administrator can terminate the quoted identifier with a closing backtick and introduce attacker-controlled structural SQL, potentially compromising database confidentiality, integrity, and availability within the application's database privileges. This issue is fixed in version 6.7.5.
