description

piflow versions 2.0.0 through 2.0.1 expose an unauthenticated command-execution path in the DeepAgents chat component. A remote party able to reach the chat service may run commands and access secrets available to the running process; exposure requires the affected endpoints to be reachable.

mitigation

Require authentication and restrict network access to the DeepAgents chat endpoints immediately. Disable or remove its shell-execution capability until an upstream fixed release is available.
