CVE-2022-4615Public exploitNetwork attack vector

Script execution via unescaped fee-sheet AJAX response

Published Dec 19, 2022 · Updated Apr 14, 2025

Reflected XSS in OpenEMR before 7.0.0.2 allows remote attackers to execute script in a user's browser through a crafted fee-sheet request. The interface/forms/fee_sheet/review/fee_sheet_ajax.php handler returns request-controlled fee-sheet data without text() output encoding. NVD identifies required user interaction; resulting script runs in the OpenEMR origin and can read or alter data available to the browser session.
