EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 54% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
