OpenEMR is a free and open source electronic health records and medical practice management application. Versions prior to 8.0.0.2 are vulnerable to stored cross-site scripting (XSS) via unescaped `portal_login_username` in the portal credential print view. A patient portal user can set their login username to an XSS payload, which then executes in a clinic staff member's browser when they open the "Create Portal Login" page for that patient. This crosses from the patient session context into the staff/admin session context. Version 8.0.0.2 fixes the issue.
