CVE-2026-48228 is a reflected cross-site scripting vulnerability in Open ISES Tickets prior to version 3.44.2. The issue exists in patient_w.php where the id and ticket_id GET parameters are not properly sanitized before being embedded into an HTML form action URL. Authenticated attackers can exploit this by crafting a malicious request containing JavaScript payloads that execute in the context of the victim's browser upon rendering the response. This can lead to script execution but requires user interaction and authentication.

Successful exploitation allows an authenticated attacker to execute arbitrary JavaScript in the victim's browser session within the affected application context. This may lead to session hijacking, unauthorized actions, or information disclosure limited to the privileges of the authenticated user. The vulnerability does not require elevated privileges but does require user interaction and authentication.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vulnerability affects versions before 3.44.2, upgrading to version 3.44.2 or later is recommended once a fix is officially released. Until then, limit exposure by restricting authenticated user access and monitoring for suspicious activity related to the id and ticket_id parameters.
