If permalinks are enabled, in many WordPress installations it is possible to enumerate all the WordPress usernames iterating through the author archives. Whenever a post is published, the username or alias is shown as the author. For example, the URL http://site.com/?author=1 will show all the posts from user id 1. Attackers can abuse this functionality to figure out which usernames are available on the site.
