Is this vulnerability remotely exploitable over the network?

Yes. If the Mesop AI sandbox Flask server is bound to a network interface reachable by an attacker, the `/exec-py` endpoint enables remote code execution via standard HTTP POST requests.

Does an attacker need valid credentials or prior access?

No. The route, as described, performs no authentication or authorization checks. Anyone who can reach the endpoint over the network can send a payload and trigger code execution.

What is the safest general fix pattern for this issue class?

The safest approach is to remove endpoints that accept and execute arbitrary code entirely. Where such capabilities are unavoidable, restrict them to isolated, non-production environments, require strong authentication, and limit them to a narrow set of pre-defined operations rather than arbitrary Python code.
