Roskus · Prospero Flow Crm · CVE-2026-19734
**Name of the Vulnerable Software and Affected Versions**
Roskus Prospero Flow CRM versions prior to 5.4.7
**Description**
An authorization bypass exists in the product management component. Authenticated users can access sensitive data, including price, cost, stock, SKU, and barcode, belonging to other companies. Additionally, users can hijack products by reassigning the `company id` using the product's numeric identifier. This occurs because the `ProductUpdateController` does not extend `MainController`, resulting in a lack of authentication checks on the read endpoint. Furthermore, the `ProductRepository::save()` function uses `Product::find($data['id'])` to retrieve records without verifying if the product belongs to the authenticated user's company before updating the `company id` variable.
**Recommendations**
Update Roskus Prospero Flow CRM to version 5.4.7 or later.
