Technical details
A reflected cross-site scripting (XSS) vulnerability exists in Vvveb CMS versions prior to 1.0.8.3. The vulnerability is located in the public product return form (`/index.php?module=user/return-form&action=save`) within the `customer_order_id` POST parameter. When an order lookup fails, the application inserts the raw input into an "Order %s not found!" error message using `sprintf` and renders it in the frontend template without proper HTML escaping. An unauthenticated attacker can exploit this by tricking a user into submitting a crafted payload, leading to arbitrary script execution in the context of the user's browser session. The issue is fixed in version 1.0.8.3.
