Is this vulnerability remotely exploitable over the internet?

Yes, if the Patient REST API is exposed over the network and reachable by clients with valid API credentials. The attack is carried out by sending crafted `_sort` values in API requests, but it remains constrained to authenticated callers with API access.

Does an attacker need administrative privileges to exploit this?

No. The vulnerability can typically be exploited by any user or integration that holds valid API credentials capable of invoking the Patient REST API endpoint. Elevated application roles are not strictly required, although broader privileges may increase the attacker's visibility and impact.

What is the safest general fix pattern for developers?

The most robust pattern is to stop using raw client input to construct SQL and instead: - Map `_sort` to a predefined set of allowed columns and directions, and - Use structured query-building utilities or ORMs that handle identifiers and ordering safely. This approach removes the ability for arbitrary expressions to influence the SQL syntax.
