Open ISES Tickets before 3.44.2 contains a reflected cross-site scripting vulnerability in add_note.php that allows authenticated attackers to inject arbitrary JavaScript by passing an unsanitized value through the ticket_id GET parameter directly into a hidden input field VALUE attribute. Attackers can craft a malicious URL containing a JavaScript payload in the ticket_id parameter that executes in the victim's browser when the URL is visited.
