CubeCart: Missing Authorization Check in customers.gdpr.inc.php Leads to Unauthorized Customer Data Deletion

EPSS Percentile

0th

CubeCart is an ecommerce software solution. Prior to 6.7.5, the GDPR tools in admin/sources/customers.gdpr.inc.php rely on page-level CC_PERM_READ access and do not require CC_PERM_DELETE for the purge, no_order_purge, or delete_guests commands. An authenticated administrator with read-only customer privileges can invoke these backend actions directly to bypass interface restrictions and irreversibly delete customer records, accounts without orders, or guest accounts, compromising data integrity and availability. This issue is fixed in version 6.7.5.
