## Affected

- givanz Vvveb: fixed in 1.0.8.4

## 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 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.
