    Changed Description Nagios Fusion versions prior to R2.1 contain a vulnerability due to the application not requiring re-authentication or session rotation when a user has enabled two-factor authentication (2FA). As a result, an adversary who has obtained a valid session could continue using the active session after the target user enabled 2FA, potentially preventing the legitimate user from locking the attacker out and enabling persistent account takeover. Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority as it is a duplicate of CVE-2025-60424.
