CVE-2026-3198

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...

CVE-2026-10803

A flaw was found in MLflow. This vulnerability stems from the use of a weak hash algorithm within the Dataset Digest Computation component. A local attacker could potentially exploit this weakness, which may impact the integrity or authenticity of data. Exploitation is considered difficult due to...

CVE-2026-2393

A flaw was found in MLflow. An authenticated attacker can exploit a Server-Side Request Forgery SSRF vulnerability by providing an unvalidated URL parameter to the createwebhook function. This allows the MLflow backend to be forced into sending HTTP requests to internal services, cloud metadata...

CVE-2026-2652

A flaw was found in mlflow. When the mlflow server is configured with basic authentication and served via uvicorn, an architectural mismatch in the FastAPI permission middleware allows unauthenticated remote attackers to bypass authentication on specific routes. This bypass enables attackers to...

CVE-2026-4137

A flaw was found in mlflow/mlflow. Insecure permissions on temporary directories allow local attackers to tamper with model artifacts, such as cloudpickle-serialized Python objects. This manipulation can lead to arbitrary code execution when the tampered artifacts are deserialized. This...

BIT-MLFLOW-2026-4035 Environment Variable Resolution Vulnerability in mlflow/mlflow

A vulnerability in mlflow/mlflow versions prior to 3.11.0 allows for the resolution of environment variables in AI Gateway secrets, which can be exploited to exfiltrate sensitive server-side environment credentials to an attacker-controlled endpoint. This issue arises because the apikey field in...

BIT-MLFLOW-2026-2651 Missing Authorization Validation in mlflow/mlflow

A vulnerability in MLflow versions =3.10.1.dev0 allows unauthorized access to multipart upload MPU endpoints when the --serve-artifacts mode is enabled. The authorization logic does not enforce resource-level permission checks for /mlflow-artifacts/mpu/ endpoints, enabling attackers to overwrite...

CVE-2026-4035

A flaw was found in MLflow. This vulnerability allows an attacker to exfiltrate sensitive server-side environment credentials. It occurs because the AI Gateway secrets can resolve environment variables, which are then sent to an attacker-controlled endpoint. This could lead to unauthorized access...

BIT-MLFLOW-2026-4137 Incomplete Fix for CVE-2025-10279: Insecure Temporary Directory Permissions in mlflow/mlflow

In mlflow/mlflow versions prior to 3.11.0, the getorcreatenfstmpdir function in mlflow/utils/fileutils.py creates temporary directories with world-writable permissions 0o777, and the createmodeldownloadingtmpdir function in mlflow/pyfunc/init.py creates directories with group-writable permissions...

BIT-MLFLOW-2026-3198 Improper Access Control in mlflow/mlflow

MLflow 3.9.0 with basic-auth --app-name basic-auth fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the BEFOREREQUESTHANDLERS dictionary in mlflow/server/auth/init.py does not include entries for ListGatewaySecretInfos, ListGatewayEndpoints, and...
