What is CVE-2026-45622?

Vvveb CMS, a user-friendly content management system with integrated page building capabilities, is susceptible to an unauthenticated reflected cross-site scripting (XSS) vulnerability. This issue occurs in the public product return form, where the customer_order_id POST parameter is improperly handled. If an order lookup fails, the error message generated incorporates this parameter directly into the frontend without proper HTML escaping. Consequently, this flaw allows attackers to inject and execute arbitrary HTML or JavaScript in the browser of the submitting user. It poses significant risks such as unauthorized access and data manipulation. This vulnerability was addressed in version 1.0.8.3 of Vvveb CMS.

Affected Version(s)
