# OpenEMR: missing permission check exposes patient clinical summaries to logged-in users

Link for people: https://infrastack.ai/live/CVE-2026-126439 (this .md is for agents)

OpenEMR before 8.5.0 does not enforce the patient-report permission in its C-CDA gateway, so any logged-in user can request a patient's clinical summary. The summary includes diagnoses, medications, lab results and identifiers.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the OpenEMR version in use; versions before `8.5.0` are affected.
- Review which accounts lack the patients/pat_rep permission but can still log in.

## Fix

- OpenEMR `8.5.0` or later (per the description; the sources do not give further detail).

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-7cfr-7h7r-f2x9

## From the sources

OpenEMR before 8.5.0 contains a missing authorization vulnerability in ccdaservice/ccda_gateway.php that fails to enforce the patients/pat_rep permission, accepting any authenticated core session. Authenticated users without patient-report permission can request the report_ccd_view action to retrieve the selected patient's C-CDA clinical summary, including diagnoses, medications, laboratory results, and identifiers.
