CVE-2026-59237: CWE-639 Authorization bypass through User-Controlled key in Roskus Prospero Flow CRM
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.
AI Analysis
Technical Summary
This vulnerability (CWE-639) in Roskus Prospero Flow CRM before version 5.5.3 allows authenticated users to bypass authorization controls in the Order and OrderItem REST API controllers. The issue arises from the use of Order::find($id) and Item::find($id) methods without restricting the query to the authenticated user's company context. Consequently, attackers can specify arbitrary numeric IDs in API requests (GET, PUT, DELETE) to access or alter data belonging to other tenants, violating tenant isolation.
Potential Impact
An authenticated user can read, modify, or delete orders and order items of other companies using the vulnerable API endpoints. This compromises data confidentiality and integrity across tenants in a multi-tenant environment, potentially leading to unauthorized data exposure and manipulation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the affected API endpoints to trusted users only and monitor for suspicious activity related to order and order item access. Implement additional access controls or request validation to enforce tenant scoping if possible.
