MLflow 3.9.0 with basic-auth (`--app-name basic-auth`) fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the `BEFORE_REQUEST_HANDLERS` dictionary in `mlflow/server/auth/__init__.py` does not include entries for `ListGatewaySecretInfos`, `ListGatewayEndpoints`, and `ListGatewayModelDefinitions`. This allows any authenticated user, regardless of their assigned permissions, to enumerate all gateway secrets, endpoints, and model definitions. This vulnerability exposes sensitive information, such as API keys, endpoint configurations, and proprietary model definitions, to unauthorized users.

A flaw was found in MLflow. When configured with basic authentication, MLflow fails to enforce proper authorization checks for several Gateway API list endpoints. This oversight allows any authenticated user, regardless of their assigned permissions, to enumerate sensitive information such as gateway secrets, endpoint configurations, and proprietary model definitions. This vulnerability leads to unauthorized information disclosure, potentially exposing critical system details and API keys.

This Moderate impact flaw affects MLflow deployments configured with basic authentication in Red Hat OpenShift AI. An authenticated user, regardless of their specific permissions, can enumerate sensitive Gateway API information, including secrets, endpoint configurations, and proprietary model definitions, leading to unauthorized information disclosure.
