Authorization Bypass Through User-Controlled Key in the contact management component in Roskus Prospero Flow CRM before 5.4.8 allows authenticated users of any company to blindly overwrite the contact data of another company and to download that contact's personal data as a vCard via the contact's numeric identifier, because the save and export operations retrieve the record without constraining the query to the authenticated user's company.
