CVE-2026-54648 · Severity: medium · CVSS 6.5 · Published 2026-09-17

CubeCart is an e-commerce platform that manages online stores and customer data. A vulnerability in the GDPR data management tools allows authenticated administrators with read-only customer access to permanently delete customer records and accounts without proper authorization. This bypasses intended interface restrictions and can result in irreversible loss of customer data and operational disruption.

## Technical details

The GDPR tools in admin/sources/customers.gdpr.inc.php fail to enforce CC_PERM_DELETE permission checks on destructive operations (purge, no_order_purge, delete_guests commands), relying only on CC_PERM_READ at the page level. An authenticated administrator with read-only customer privileges can invoke these backend actions directly via HTTP requests to bypass interface restrictions and irreversibly delete customer records. The vulnerability requires an existing admin session with at least read access to the customer GDPR section. The fix adds explicit CC_PERM_DELETE checks to gate each destructive branch while preserving read-only access to GDPR reports.
