CVE-2026-49223: CWE-639: Authorization Bypass Through User-Controlled Key in givanz Vvveb
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.
AI Analysis
Technical Summary
CVE-2026-49223 is an authorization bypass vulnerability in the Vvveb CMS backend prior to version 1.0.8.4. The vulnerability exists because the product_review_id parameter in SQL queries is user-controlled and the system fails to verify that the product_review.product_id corresponds to the current admin_id (vendor). Consequently, a low-privileged vendor can access and manipulate product reviews of other vendors, including reading pending reviews, changing review status, editing content, or deleting reviews. This compromises the integrity and visibility of product reviews. The vulnerability is tracked as CWE-639 (Authorization Bypass Through User-Controlled Key) and has a CVSS 3.1 base score of 7.6 (high severity).
Potential Impact
An attacker with low vendor privileges can bypass authorization controls to access and manipulate product reviews belonging to other vendors. This includes reading sensitive review content and author information, altering review statuses, editing review content, or deleting reviews. The impact affects confidentiality (limited to review content), integrity (high impact due to unauthorized modifications), and availability (low impact). This undermines trust in product reviews and can affect ecommerce operations relying on review accuracy.
Mitigation Recommendations
A fix is available in Vvveb version 1.0.8.4. Users of affected versions should upgrade to 1.0.8.4 or later to remediate this vulnerability. No additional mitigation guidance is provided or required beyond applying the official update.
