Description
loonflow before r3.2.3 contains a missing authorization vulnerability in TicketFlowHistoryView that allows any authenticated user to read other users' ticket flow history by supplying a ticket UUID. Attackers can request the ticket_flow_history endpoint, which skips ticket_view_permission_check, to obtain approval comments and processor names, emails and phone numbers.
