Prior to 8.3.0, the search_persons action in library/ajax/person_search_ajax.php validates CSRF but does not perform an AclMain authorization check before searching the person and patient_data 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.
