Is this vulnerability remotely exploitable?

Yes. If the Flask endpoint providing `update_sql` or `run_sql` is reachable over the network, a remote attacker can attempt to craft requests that cause SSRF, leveraging the server to reach other targets.

Does exploitation require authentication or special privileges?

It depends on how the deployment is configured. If the endpoint is unauthenticated or weakly protected, any remote party with network access may attempt exploitation. Even with authentication, any user who can hit the endpoint and control its parameters could potentially trigger SSRF.

What is the safest general fix pattern?

Decouple user input from server-controlled network destinations. Use fixed, configuration-driven connection targets for SQL or data sources and enforce rigorous allowlists. Reject user-controlled URLs or hostnames and ensure that all server-originated requests can only go to predetermined, vetted endpoints.
