CVE-2026-3198
No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
