Technical details
The delete-note handler in admin/sources/orders.index.inc.php fails to verify the CC_PERM_DELETE permission flag before removing records from the CubeCart_order_notes table. The vulnerable code checks only for the presence of order_id and delete-note GET parameters, allowing any authenticated admin session to invoke the handler and delete notes belonging to any order. The fix (applied in 6.7.5) adds a permission check via Admin::getInstance()->permissions('orders', CC_PERM_DELETE) before permitting deletion. This is an authenticated, network-reachable privilege-escalation vulnerability with low attack complexity; an admin lacking delete privileges can directly call the vulnerable handler with valid order identifiers.
