Technical details

An Insecure Direct Object Reference (IDOR) vulnerability (CWE-639) exists in the Order and OrderItem REST API controllers of Roskus Prospero Flow CRM. The affected controllers (OrderReadController, OrderUpdateController, OrderItemReadController, OrderItemUpdateController, and OrderItemDeleteController) use direct database lookups like Order::find($id) without verifying that the requested record belongs to the authenticated user's company (tenant). Because IDs are sequential integers and the system lacks rate limiting, a remote authenticated attacker can enumerate and manipulate orders across the entire platform. This allows for the unauthorized reading, modification, and deletion of cross-tenant data, including customer PII and order statuses. The issue is fixed in version 5.5.3 by adding company_id scoping to the database queries.
