Trudesk through 1.2.11 Authorization Bypass via Ticket Update API Endpoints
Description

Trudesk through 1.2.11 contains an authorization bypass vulnerability that allows any authenticated user to modify tickets outside their groups via PUT /api/v1/tickets/:id and PUT /api/v2/tickets/batch. Attackers can supply arbitrary ticket ObjectIds to change status, subject, group, priority or assignee, or mass-close tickets, since only the default tickets:update role grant is checked.
