NVD Description
Note: Versions mentioned in the description apply only to the upstream mlflow package and not the mlflow package as distributed by Chainguard.
See How to fix? for Chainguard relevant fixed versions and status.
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.
