Description
CVE-2026-19433 is an authorization bypass vulnerability in Roskus Prospero Flow CRM before version 5.4.8. It affects the contact management component, allowing authenticated users from any company to overwrite contact data of other companies and download personal contact data as vCards. This occurs because save and export operations do not restrict queries to the authenticated user's company.
