Name of the Vulnerable Software and Affected Versions MLflow version 3.9.0
Description When using basic-auth (--app-name basic-auth), the software fails to enforce authorization checks for several Gateway API 'list' endpoints. The BEFORE REQUEST HANDLERS dictionary in mlflow/server/auth/ init .py lacks entries for the functions ListGatewaySecretInfos(), ListGatewayEndpoints(), and ListGatewayModelDefinitions(). This allows any authenticated user to enumerate all gateway secrets, endpoints, and model definitions, regardless of their permissions, potentially exposing sensitive data such as API keys and proprietary model configurations.
Recommendations For version 3.9.0, restrict access to the Gateway API 'list' endpoints or avoid using the basic-auth configuration until a fix is applied. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
