What is CVE-2026-54647?
CVE-2026-54647 is a high-severity SQL injection vulnerability in cubecart v6, published on 17 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
