Vulnerability Title
Vvveb product authorization bypass allows Vendors to read, duplicate, or delete other Vendors' products
Source: CVE Program / CVE List V5
Vulnerability 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.
