PYSEC-2026-2654 MLflow allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem

A vulnerability in the createmodelversion handler of mlflow/server/handlers.py in mlflow/mlflow versions 3.9.0 and earlier allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem. The issue arises when a CreateModelVersion request includes the tag...

CVE-2026-8147

A flaw was found in MLflow. When authentication is enabled, any authenticated user can bypass experiment-level authorization controls on trace API endpoints. This is due to missing authorization validators, allowing unauthorized reading, deleting, and modifying of traces. This vulnerability can...

CVE-2026-13484

A flaw was found in MLflow. This vulnerability, located in the Experiment-scoped Label Schema CRUD API, allows a remote attacker to exploit missing authorization. This could lead to unauthorized access or manipulation of data within the affected component. The attack has a high complexity, making...

PYSEC-2026-417 Remote Code Execution due to Full Controled File Write in mlflow

The mlflow web server includes tools for tracking experiments, packaging code into reproducible runs, and sharing and deploying models. As this vulnerability allows to write / overwrite any file on the file system, it gives a lot of ways to archive code execution like overwriting /home//.bashrc. ...

CVE-2026-13484

A vulnerability has been found in MLflow up to 4666cffc7912ea606d592fc38d6a75e2935f65e7. The impacted element is an unknown function of the component Experiment-scoped Label Schema CRUD API. Such manipulation leads to missing authorization. It is possible to launch the attack remotely. A high...

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...
