Vulnerability Title
Vvveb product review authorization bypass allows Vendors to read, approve, edit, or delete reviews under 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 review operations allow a low-privileged Vendor to manage reviews under another Vendor's products. 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. An attacker can read pending review content, ratings, author information, and moderation state, change review status, edit review content, or delete reviews, manipulating product review visibility and integrity. This issue is fixed in version 1.0.8.4.
