What is CVE-2026-54646?
CVE-2026-54646 is a high-severity SQL injection vulnerability in cubecart v6, published on 17 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
