## Technical details

A Stored Cross-Site Scripting (XSS) vulnerability exists in Pandora FMS due to improper neutralization of user-supplied input during web page generation (CWE-79). The vulnerability is located in the event comments component. An authenticated attacker with low privileges can inject malicious JavaScript into the comment field. When other users, including administrators, view the affected event, the script executes in the context of their browser session. This can lead to session hijacking, unauthorized configuration changes, or further privilege escalation. The issue affects versions 777 through 800; users should update to version 800.1 or later.
