What is CVE-2026-48226?

Open ISES Tickets prior to version 3.44.2 contains a reflected cross-site scripting vulnerability in the os_watch.php script. This flaw enables authenticated attackers to inject arbitrary JavaScript by sending unsanitized input through the 'ref' and 'mode_orig' POST parameters.
