CVE-2026-48215 is a reflected cross-site scripting vulnerability affecting Open ISES Tickets prior to version 3.44.2. The issue arises because the frm_id POST parameter is directly embedded into an HTML form input value without proper neutralization, enabling authenticated attackers to inject and execute arbitrary JavaScript in the context of the victim's browser. This can lead to typical XSS impacts such as session hijacking or unauthorized actions if exploited. The vulnerability requires user interaction and authentication to be exploited. The CVSS 4.0 vector indicates network attack vector, low complexity, no privileges required, but user interaction is needed.

Successful exploitation allows an authenticated attacker to execute arbitrary JavaScript in the victim's browser session when viewing the affected page. This can lead to theft of sensitive information, session hijacking, or other malicious actions performed in the context of the victim's session. The vulnerability is rated medium severity with a CVSS score of 5.1. There are no reports of active exploitation in the wild.
