CVE-2026-59237 Details
Description
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.
An authorization bypass vulnerability has been identified in the Order and OrderItem REST API controllers of Roskus Prospero Flow CRM, in versions after 4.6.0 and prior to 5.5.3. This vulnerability allows remote, authenticated users to read, modify, and delete orders and order items across different companies (tenants). The issue arises because the API endpoints do not properly scope data access by the authenticated user's company, enabling unauthorized cross-tenant actions. Exploitation involves supplying a sequential numeric ID to the vulnerable API endpoints, which are then processed without company-specific restrictions, leading to unauthorized access and modification of sensitive data.
Users are advised to upgrade to Roskus Prospero Flow CRM version 5.5.3 or later, where this vulnerability has been fixed.
