CVE-2026-46408 | BDVDB-2026-333641 Detail

givanzVvveb

Description#

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.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact high, availability impact low. Attack vector: network.
