This affects the function launch_goal of the file im_client/communication/communication_layer.py of the component Collaboration Layer. Performing a manipulation of the argument max_turns results in infinite loop. The attack may be initiated remotely. The exploit is now public and may be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet."
