Description
wp-includes/rest-api/endpoints/class-wp-rest-users-controller.php in the REST API implementation in WordPress 4.7 before 4.7.1 does not properly restrict listings of post authors, which allows remote attackers to obtain sensitive information via a wp-json/wp/v2/users request.
Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
