## What is CVE-2026-49228?

CVE-2026-49228 is a high-severity missing authorization vulnerability in givanz Vvveb, published on 18 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.4, Vvveb backend product operations allow a low-privileged Vendor to access products owned by another Vendor. The admin/controller/product/products.php controller accepts a caller-controlled product_id for duplicate and delete actions, and admin/sql/sqlite/product.sql loads and mutates products without consistently applying the current admin_id when view_other_products or edit_other_products is absent. An attacker can read product details, duplicate products, or delete products and related catalog data, exposing commercial information and causing unauthorized copies, catalog pollution, data loss, or business disruption. This issue is fixed in version 1.0.8.4.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key)
