A flaw was found in MLflow. A user without proper permissions to an experiment can exploit an authorization bypass in the AJAX endpoint, which is used for downloading saved model artifacts. This missing access-control validation allows the unauthorized user to directly query the endpoint and retrieve model artifacts they are not authorized to access, leading to information disclosure.
