# OpenEMR: missing ownership checks let users read and overwrite other patients' records

Link for people: https://infrastack.ai/live/CVE-2026-124459 (this .md is for agents)

OpenEMR before 8.3.0 has encounter-form view and save endpoints that do not check patient or encounter ownership. An authenticated clinical user can change sequential form IDs in requests such as soap/view.php and save.php to read and overwrite other patients' clinical records.

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

## How to check

- Check the installed OpenEMR version against the fixed version in the product ranges (unknown in sources)
- Confirm whether clinical users can reach soap/view.php and save.php for patients outside their care

## Fix

- OpenEMR: `8.3.0` or later (per the advisory range 'before 8.3.0')

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/openemr/openemr/security/advisories/GHSA-3mg9-27fw-m9j6
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/openemr-before-8.3.0-cross-patient-idor-via-encounter-form-viewers-and-save-handlers

## From the sources

OpenEMR before 8.3.0 contains an insecure direct object reference vulnerability in many encounter-form view and save endpoints that lack patient/encounter ownership checks. Authenticated clinical users can enumerate sequential form id values in requests such as soap/view.php and save.php to read and overwrite other patients' clinical records.
