CVE-2022-4504Network attack vector

Authenticated data alteration and service interruption

Published Dec 15, 2022 · Updated Apr 14, 2025

Improper input validation in OpenEMR before 7.0.0.2 allows remote authenticated users to alter data and interrupt the service. The public record does not identify the affected request, component, or validation failure, and the shared fix commit changes four output-handling paths. Low-privileged authenticated access is required; published impact is limited to integrity loss and a service interruption.
