str: normalized = endpoint.strip().lower().rstrip(".") if normalized not in ALLOWED_ENDPOINTS: raise ValueError("Unsupported JF Tech API endpoint") return normalized ``` Apply validation immediately when loading the environment configuration: ```python endpoint = validate_endpoint( os.environ.get("JF_ENDPOINT", "api.jftechws.com") ) ``` Additional hardening should include: 1. Prefer a predefined region selector, such as `international` or `china`, over an arbitrary hostname. 2. Reject endpoint values containing schemes, credentials, ports, paths, queries, or fragments. 3. Reject IP literals and suffix-based lookalikes such as `api.jftechws.com.attacker.example`. 4. Continue requiring HTTPS and rely on normal certificate and hostname verification. 5. Avoid logging full device tokens or signed playback URLs. 6. Document that only the two declared official hosts are accepted. 7. Add automated tests proving that arbitrary hosts and hostname lookalikes are rejected. ]]>
