Executive brief
Roskus Prospero Flow CRM, a customer relationship management platform, contains a security flaw in how it handles order data. An authenticated user can view, change, or delete orders and order items belonging to other companies using the system by simply guessing sequential ID numbers. This could lead to the exposure of sensitive customer personal information (PII), including names, addresses, and contact details, as well as the unauthorized modification of business order records.
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.
