CVE-2024-13996

Nagios XI < 2024R1.1.3 Session Not Invalidated After Password Change

Published Oct 30, 2025 CVSS 4.0 · 9.2 Critical EPSS 1.1% KEV · Not listed
Description
Nagios XI versions prior to 2024R1.1.3 did not invalidate all other active sessions for a user when that user's password was changed. As a result, any pre-existing sessions (including those potentially controlled by an attacker) remained valid after a credential update. This insufficient session expiration could allow continued unauthorized access to user data and actions even after a password change.
