CVE-2026-49225: 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 revision operations allow a low-privileged Vendor to access revisions for products owned by another Vendor. The admin/controller/product/revisions.php route reuses admin/controller/content/revisions.php, while admin/sql/sqlite/product_content_revision.sql trusts caller-controlled product_id, language_id, and created_at values without applying the current admin_id to revision reads, restores, and deletes. An attacker can read historic product content, restore a revision over another Vendor's live product content, or delete revision records, exposing private copy, corrupting product pages, and removing audit history. This issue is fixed in version 1.0.8.4.
AI Analysis
Technical Summary
CVE-2026-49225 is an authorization bypass vulnerability in the Vvveb CMS product revision backend prior to version 1.0.8.4. The vulnerability arises because the admin/controller/product/revisions.php route reuses code from admin/controller/content/revisions.php and the underlying SQLite queries trust caller-controlled product_id, language_id, and created_at parameters without enforcing that the current admin_id matches the product owner. This allows a low-privileged vendor to read historic product content, restore revisions over other vendors' live products, or delete revision records. The flaw impacts confidentiality, integrity, and auditability of product data. The issue is resolved in version 1.0.8.4.
Potential Impact
An attacker with low privileges as a vendor can bypass authorization controls to access confidential historic product content of other vendors, overwrite live product content by restoring unauthorized revisions, and delete revision audit records. This compromises data confidentiality, integrity, and accountability within the CMS product revision system. The vulnerability has a high CVSS score of 8.3, reflecting its potential to cause significant impact on product data security and trustworthiness.
Mitigation Recommendations
Upgrade Vvveb to version 1.0.8.4 or later, where this authorization bypass vulnerability is fixed. No other mitigation or workaround is documented. Patch status is confirmed fixed in 1.0.8.4.
