Reflected XSS in OpenEMR Foundation OpenEMR before 6.0.0.4 allows remote authenticated users to execute script via a crafted link. The postcalendar_admin_categoriesConfirm() function inserts an untrusted calendar category name into an HTML confirmation without output encoding. Exploitation requires calendar-administration access and user interaction; injected script executes with the victim's OpenEMR browser-session privileges.
