CVE-2026-49221: 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 digital asset operations allow a low-privileged Vendor to access digital assets linked to another Vendor's products. The admin/controller/product/digital-asset.php and admin/controller/product/digital-assets.php controllers and the admin/sql/sqlite/digital_asset.sql data queries use a caller-controlled digital_asset_id without consistently enforcing the current admin_id ownership boundary. An attacker can list assets, read asset names and file metadata, edit asset metadata, or delete asset records, which can disclose private product metadata, corrupt resource links, and cause data loss. This issue is fixed in version 1.0.8.4.
AI Analysis
Technical Summary
CVE-2026-49221 is an authorization bypass vulnerability in the Vvveb CMS by givanz affecting versions before 1.0.8.4. The backend digital asset management functionality does not properly enforce ownership checks on the digital_asset_id parameter in admin/controller/product/digital-asset.php, admin/controller/product/digital-assets.php, and related SQL queries. This allows a low-privileged vendor user to access and manipulate digital assets linked to other vendors' products, potentially disclosing private product metadata, corrupting resource links, and causing data loss. The vulnerability is tracked as CWE-639 (Authorization Bypass Through User-Controlled Key).
Potential Impact
An attacker with low privileges can bypass authorization controls to access and modify digital assets of other vendors. This can lead to unauthorized disclosure of private product metadata, corruption of resource links, and deletion of asset records, resulting in data loss and operational disruption.
Mitigation Recommendations
This vulnerability is fixed in Vvveb version 1.0.8.4. Users should upgrade to version 1.0.8.4 or later to remediate this issue. No official patch or temporary fix details are provided beyond this version update. Since this is not a cloud service, remediation depends on applying the vendor's fixed version.
