CVE-2026-71211 · mlflow - Unvalidated Gateway Secret api_base Enables SSRF via Gateway Proxy Endpoint

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
