CVE-2026-46408: Givanz Vvveb

High severity, CVSS 7.6. EPSS: 0.3% chance of exploitation in the next 30 days.

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.3, the checkout endpoint accepts a user-controlled cart_id and uses it to enter the payment flow without verifying cart ownership. A logged-in attacker can therefore reuse another user's cart data in their own checkout session. This vulnerability is fixed in 1.0.8.3.

• Givanz Vvveb: before 1.0.8.3 (fixed in 1.0.8.3)
