CVE-2025-54821

Administrator trusted-host bypass via crafted CLI command

Published Nov 18, 2025 · Updated Nov 18, 2025

Improper privilege management in affected Fortinet FortiOS, FortiPAM, and FortiProxy releases lets local users bypass trusted hosts. The SSH CLI accepts a crafted command without correctly enforcing the configured trusted-host policy; Fortinet has not disclosed the specific faulty check. Administrator privileges and high-complexity local access are required; the bypass permits CLI activity from a host the policy should reject.
