## Overview

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, library/ajax/set_pt.php allows any authenticated user to set an arbitrary patient identifier in the active session without an ACL check, and interface/patient_file/download_template.php trusts that session value while enforcing only CSRF validation. A low-privilege user can select another patient and download a rendered document template containing the patient's demographics, encounter information, allergies, medications, and problem list despite lacking patients/docs access. This issue is fixed in version 8.3.0.

## Affected

- `openemr < 8.3.0`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
