OpenEMR's Eye Exam View Trusts form_id Without Verifying Patient/Encounter Ownership

Assigner: GitHub_M
Reserved: 25.02.2026 Published: 26.02.2026 Updated: 26.02.2026

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.
