Check it with your coding agent
It reads this page and tells you if your code or app is affected.
Clinics and hospitals that run OpenEMR with the patient portal enabled are exposed, because any logged-in patient can trigger server-side requests. Installs without the patient portal, or with patient accounts disabled, are less exposed. Cloud-hosted installs may expose metadata endpoints, which raises the impact.
Not affected if managed-hosting, patient-portal-disabled
