What is CVE-2026-19734?
CVE-2026-19734 is a high-severity missing authorization vulnerability in Roskus Prospero Flow CRM, published on 13 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-639
