Description

CubeCart is an ecommerce software solution. Prior to 6.6.0, a Stored Cross-Site Scripting (XSS) vulnerability exists in CubeCart v6.x. An attacker with administrative privileges can inject malicious JavaScript payloads into multiple fields during the creation or modification of a product. These payloads are stored in the database and executed whenever a user (customer or another administrator) views the affected product pages, which could lead to session hijacking or unauthorized actions. This vulnerability is fixed in 6.6.0.
