CVE-2026-19539
Authorization Bypass Through User-Controlled Key in the ticket management component in Roskus Prospero Flow CRM before 5.4.9 allows authenticated users of any company to read the full content (title, description, and attachments) of tickets belonging to another company, to hijack another company's tickets by reassigning their company_id, and to delete another company's tickets without any authorization check, via the ticket's numeric identifier, because the read and save operations retrieve the record without constraining the query to the authenticated user's company, and the delete controller type-hints a generic Illuminate\Http\Request instead of the TicketDeleteRequest that would enforce the required permission.
