A command injection vulnerability exists in mlflow/mlflow versions before v3.7.0, specifically in the "mlflow/sagemaker/__init__.py" file at lines 161-167. The vulnerability arises from the direct interpolation of user-supplied container image names into shell commands without proper sanitization, which are then executed using "os.system()". This allows attackers to execute arbitrary commands by supplying malicious input through the "--container" parameter of the CLI. The issue affects environments where MLflow is used, including development setups, CI/CD pipelines, and cloud deployments.
