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.
AnalysisAI
Insecure direct object reference in Vvveb CMS prior to 1.0.8.4 allows any authenticated Vendor-role user to read, restore, and delete product revision records belonging to other Vendors by supplying arbitrary caller-controlled product_id values to the backend revision controller. All Vvveb multi-vendor deployments running versions before 1.0.8.4 are affected across MySQL, PostgreSQL, and SQLite database backends. …
