MEDIUMPre-NVD 6.56.5—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 82% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
