AI-suggested

If you cannot patch yet, restrict access to trusted users only and monitor for suspicious use of the 'Grpc-Metadata-USER' header in requests. Avoid exposing the Velociraptor GUI to untrusted networks.

Description

An authenticated attacker can spoof another GUI user's identity by sending their request with the custom header \"Grpc-Metadata-USER\". This can lead to an account takeover attack from a user with low privileges to administrator.
