The fix

We hold no Microsoft remediation data for CVE-2026-54647, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

CubeCart is an ecommerce software solution. Prior to 6.7.5, admin/sources/settings.index.inc.php directly concatenates the administrator-controlled download_expire POST parameter into a raw UPDATE statement for CubeCart_downloads without numeric validation. An authenticated administrator can supply a comma-delimited value that changes the SET clause because HTML sanitization does not neutralize SQL syntax, allowing manipulation of database columns and potentially other data within the application's database privileges. This issue is fixed in version 6.7.5.
