CVE-2026-2652

A vulnerability in mlflow/mlflow versions 3.9.0 and earlier allows unauthenticated access to certain FastAPI routes when the server is started with authentication enabled --app-name basic-auth and served via uvicorn ASGI. The FastAPI permission middleware only enforces authentication on /gateway/...

CVE-2026-4137

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-2026-4035 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...

CVE-2026-4035

CVE-2026-4035 affects mlflow/mlflow versions before 3.11.0. The API for AI Gateway secrets allows the api_key field to contain $ENV_VAR references, which are resolved against the MLflow server environment at runtime. Attackers can exfiltrate server-side environment credentials (e.g., AWS_ACCESS_K...

CVE-2026-2614

A flaw was found in mlflow. An unauthenticated remote attacker can exploit a vulnerability in the createmodelversion handler by including a specific tag, mlflow.prompt.isprompt, in a CreateModelVersion request. This bypasses source path validation, allowing the attacker to specify an arbitrary...
