Deeper analysis
Nagios XI versions through 5.8.5 contain a cross-site scripting vulnerability in the scheduled reports feature. An authenticated user can supply HTML tags that are later rendered in notification emails sent from the application's official address, altering message formatting and content without requiring user interaction.
An attacker with a low-privileged account reachable over the network can exploit the flaw to tamper with the integrity of outbound administrative emails. The attack achieves modification of email appearance or embedded content while leaving confidentiality and availability unaffected, consistent with the CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N.
Vendor change logs reference fixes in subsequent Nagios XI releases, directing administrators to upgrade beyond 5.8.5. The associated EPSS score has remained flat at 0.0509 with no material increase after disclosure.
