NVD description
MLflow's AI Gateway accepts an auth_config.api_base value when creating a gateway secret (mlflow/server/handlers.py, _create_gateway_secret) with no validation of scheme, host, or IP range; the value is stored verbatim. The gateway proxy endpoint (mlflow/server/gateway_api.py, raw_proxy) subsequently issues an HTTP request to that stored api_base plus a caller-supplied path and returns the full response body.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep MLflow off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
