Stored XSS in Nagios XI 2024R1.1.4 allows remote authenticated users to execute scripts in another user's browser through a host alias. The Account Settings Name field stores an unneutralized alias and renders it on Host Status Detail and Host Group pages, where injected HTML or JavaScript becomes executable page content.
