# OpenEMR: patient portal lets logged-in patients read other patients' problem lists

Link for people: https://infrastack.ai/live/CVE-2026-124470 (this .md is for agents)

OpenEMR before 8.3.0 has a broken access control flaw in its patient portal report page, portal/report/portal_custom_report.php. An authenticated portal patient can enumerate sequential issue IDs to read other patients' problem titles, clinical notes, ICD diagnosis codes and contraceptive records.

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

## How to check

- Check the OpenEMR version in the installed application; versions below `8.3.0` are in the affected range.
- Confirm whether the patient portal is enabled for patients on the instance.

## Fix

- OpenEMR: move to `8.3.0` or later.

## Timeline

## From the sources

OpenEMR before 8.3.0 contains a broken object level authorization vulnerability in portal/report/portal_custom_report.php that allows authenticated portal patients to read other patients' problem list entries. Attackers can enumerate sequential IDs in issue_ parameter names to retrieve other patients' problem titles, clinical notes, ICD diagnosis codes, and IPPF contraceptive records.
