## Technical details

An authorization bypass vulnerability in the hd_ticket.api.new endpoint fails to validate the raised_by parameter, allowing authenticated users to specify arbitrary customer emails when creating tickets. An attacker with valid portal credentials can call this endpoint with a victim's email address to create tickets appearing to be from that customer, then use get_ticket_activities to read responses. The vulnerability requires authentication but allows impersonation of any customer account.
