# OpenEMR: missing authorization lets any logged-in user read and edit patient billing notes

Link for people: https://infrastack.ai/live/CVE-2026-124472 (this .md is for agents)

OpenEMR, an electronic health records system, has a missing authorization check in its billing EOB patient note page. Any authenticated user, including low-privilege accounts, can read and modify confidential patient billing notes by changing the patient_id value.

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

## How to check

- Check the installed OpenEMR version in the application's version settings or in the `version` file of the install.
- Look for `interface/billing/sl_eob_patient_note.php` in the install directory.

## Fix

- OpenEMR versions before `8.3.0` are affected; move to `8.3.0` or later.

## Documents

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-74j7-7q95-rvxg
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/openemr-before-8.3.0-missing-authorization-via-sl-eob-patient-note-php

## From the sources

OpenEMR before 8.3.0 contains a missing authorization vulnerability in interface/billing/sl_eob_patient_note.php that allows any authenticated user to read and modify patient billing notes. Attackers with low-privilege accounts can enumerate the patient_id parameter and submit POST requests using the embedded CSRF token to view or tamper with confidential billing data.
