Is this vulnerability remotely exploitable?

Yes. The vulnerable endpoint is accessible over the network, and attackers can interact with /purchase.php remotely as long as they can reach the web application.

Does an attacker need authenticated access?

That depends on how the application is configured and whether /purchase.php requires login. If the endpoint is reachable without authentication, exploitation can be fully unauthenticated; otherwise, an attacker would need at least low-privileged access.

What is the safest general fix pattern for this issue?

Replace any dynamic SQL string construction involving custom (and similar parameters) with prepared statements or parameterized queries, combined with strict server-side input validation and principle-of-least-privilege for the database account.
