## Overview

OpenEMR before 8.4.0 contains an arbitrary local file read vulnerability in REST document download, where the controller passes stored uploaded document bytes to Symfony's BinaryFileResponse as a filesystem path instead of returning them as content. Authenticated users with document upload and download access can upload a document containing an absolute pathname, such as the sqlconf.php location, then download it to read server files and recover database credentials.

## Affected

- `openemr < 8.4.0`
