Authorization Bypass Through User-Controlled Key (CWE-639) in the Order and OrderItem REST API controllers in Roskus Prospero Flow CRM before 5.5.3 allows a remote, authenticated user to read, modify, and delete orders and order items belonging to any other company (tenant) via a sequential numeric {id} supplied to GET /api/order/{id}, PUT /api/order/{id}, GET /api/order-item/{id}, PUT /api/order-item/{id}, or DELETE /api/order-item/{id}, because the controllers resolve records with Order::find($id) / Item::find($id) without scoping by the authenticated user's company.
