Technical summary

The Vvveb CMS has a vulnerability that allows low-privileged vendors to manage reviews under another vendor's products, potentially impacting review visibility and integrity. The vulnerability arises from the Vvveb backend product review operations, which permit a low-privileged Vendor to manage reviews under another Vendor's products. This issue is fixed in version 1.0.8.4. The admin/sql/sqlite/product_review.sql queries accept a caller-controlled product_review_id and do not verify product_review.product_id against product.admin_id for the current admin_id.
