CubeCart is an ecommerce software solution. Prior to 6.7.5, the delete-note handler in admin/sources/orders.index.inc.php verifies only the presence of order_id and delete-note parameters before deleting records from CubeCart_order_notes, without requiring CC_PERM_DELETE for orders. An authenticated administrator lacking order modification privileges can directly invoke the handler with valid identifiers and delete order-history notes, removing operational records and audit-trail data. This issue is fixed in version 6.7.5.
