Vulnerability in Roskus Prospero Flow CRM (CVE-2026-19734)
Summary
Vulnerability in Roskus Prospero Flow CRM (CVE-2026-19734). Risk of unauthorized operations or information disclosure. Exploitable via ProductUpdateController.
Original description
The description as published by the source.
Missing Authorization and Authorization Bypass Through User-Controlled Key in the product management component in Roskus Prospero Flow CRM before 5.4.7 allows authenticated users of any company to read the full sensitive data (price, cost, stock, SKU, and barcode) of another company's product and to hijack that product by reassigning its company_id, via the product's numeric identifier, because ProductUpdateController did not extend MainController and therefore required no authentication check on the read endpoint, and ProductRepository::save() retrieved the record via Product::find($data['id']) without constraining the query to the authenticated user's company before overwriting its company_id.
