GHSA-xhfm-5pwg-3cxv: OpenEMR: Missing authorization in person-search AJAX leaks patient demographics (name, DOB, phone, email)

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.3.0, the searchpersons action in library/ajax/personsearchajax.php validates CSRF but does not perform an AclMain authorization check before searching the person and patientdata tables. A low-privilege authenticated user can iterate name prefixes and receive patient first and last names, dates of birth, gender, phone numbers, and email addresses in JSON responses. This issue is fixed in version 8.3.0.
