Overview

Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the gRPC API server when it is initialized without any authentication mechanism. An attacker can execute unauthorized administrative actions, such as banning or unbanning arbitrary IP addresses and triggering external script execution, by sending crafted requests to the exposed API. This can result in disruption of network services and execution of arbitrary scripts. This is only exploitable if the attacker has local network access to the API server.
