CVE-2025-34283Network attack vector

API key disclosure via unauthorized Neptune display

Published Oct 30, 2025 · Updated Oct 30, 2025

Information disclosure in Nagios XI before 2024R1.4.2 allows remote authenticated users to view API keys through Neptune themes. The Neptune interface renders another user's or the current user's API key without enforcing API-access authorization. An authenticated account without API privileges is sufficient; exposure is limited to API-key confidentiality, with no reported data modification or service interruption.
