Technical description

OpenEMR is a free and open source electronic health records and medical practice management application. In versions up to and including 8.0.0, the eye exam (eye_mag) view loads data by `form_id` (or equivalent) without verifying that the form belongs to the current user’s patient/encounter context. An authenticated user can access or edit any patient’s eye exam by supplying another form ID; in some flows the session’s active patient may also be switched. A fix is available on the `main` branch of the OpenEMR GitHub repository.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
