How to fix?

Upgrade @grackle-ai/powerline to version 0.70.1 or higher.

Overview

@grackle-ai/powerline is a gRPC PowerLine server for Grackle AI agent integration

Affected versions of this package are vulnerable to Missing Authentication for Critical Function in the PowerLine gRPC server when when --token is not provided and GRACKLE_POWERLINE_TOKEN is not set. An attacker can gain unauthorized access, spawn agent sessions, retrieve credential tokens, and execute arbitrary code by connecting to the exposed service. This is only exploitable if the service is bound to a non-localhost interface or is otherwise accessible from outside the local machine.
