What is CVE-2026-48223?

Open ISES Tickets before version 3.44.2 is vulnerable to a reflected cross-site scripting flaw in the ics213rr.php file. This issue enables authenticated attackers to inject arbitrary JavaScript by exploiting the frm_add_str POST parameter, which accepts unsanitized input. When a malicious request is crafted with a JavaScript payload, it gets executed in the victim's browser upon rendering the response, potentially compromising user data and session integrity.
