Authentication Bypass on FastAPI Routes (Job API, OTel API) When Basic Auth Enabled

Summary When MLflow is started with authentication enabled --app-name basic-auth and served via uvicorn ASGI, the FastAPI permission middleware only enforces authentication on /gateway/ routes. All other FastAPI routes -- including the Job API /ajax-api/3.0/jobs/ and the OpenTelemetry trace...

Authorization Bypass in SearchModelVersions Allows Any Authenticated User to Enumerate All Model Versions Regardless of Permissions

Summary MLflow's SearchModelVersions REST API endpoint GET /api/2.0/mlflow/model-versions/search and GraphQL query mlflowSearchModelVersions lack per-model authorization checks when basic auth is enabled. Any authenticated user can enumerate ALL model versions across ALL registered models,...

Arbitrary File Read via Prompt Tag Source Validation Bypass in CreateModelVersion

The createmodelversion handler in mlflow/server/handlers.py uses a client-controlled tag to decide whether to skip source path validation. When a CreateModelVersion request includes the tag mlflow.prompt.isprompt, the helper ispromptrequest returns True, and the entire source validation block...

SSRF in MLflow via user-controlled webhook URL parameter

Description A Server-Side Request Forgery SSRF vulnerability exists in the webhook creation functionality of MLflow. The createwebhook handler accepts a user-controlled url parameter and stores it without any validation. When webhooks are tested or triggered, the sendwebhookrequest function sends...
