Vulnerability Description

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, an authorization bypass in the dated reminders log allows any authenticated non-admin user to view reminder messages belonging to other users, including associated patient names and free-text message content, by crafting a GET request with arbitrary user IDs in the `sentTo[]` or `sentBy[]` parameters. Version 8.0.0.2 fixes the issue.
