# OpenEMR: any logged-in user can read and overwrite patient documents

Link for people: https://infrastack.ai/live/CVE-2026-124461 (this .md is for agents)

OpenEMR before 8.3.0 lets any authenticated user supply an arbitrary doc_id to library/ajax/upload.php and read or overwrite that document. Low-privilege users can enumerate document IDs to expose patient health information and alter medical records across all patients.

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

## How to check

- Check the installed OpenEMR version; versions before `8.3.0` are in scope.
- Review access to `library/ajax/upload.php` in your web server logs for fetch and save requests with varying doc_id values.

## Fix

- OpenEMR: move to `8.3.0` or later.

## From the sources

OpenEMR before 8.3.0 contains a missing authorization vulnerability in library/ajax/upload.php that allows any authenticated user to read and overwrite document data by supplying an arbitrary doc_id. Low-privilege users can enumerate doc_id values with the fetch and save actions to disclose patient health information and tamper with medical records across all patients.
