Description:Summary:
WordPress platforms use a parameter called `author'. This parameter
accepts integer values and represents the `User ID' of users in the
web site. For example: http://www.example.com/?author=1

1. User ID values are generated consecutively.

2. When a valid User ID is found, WordPress redirects to a web page
with the name of the author.

Vulnerability Impact:

1. The query response discloses whether the User ID is enabled.

2. The query response leaks (by redirection) the User Name
corresponding with that User ID.

Solution:
No known solution was made available for at least one year since the disclosure of this vulnerability.
Likely none will be provided anymore. General solution options are to upgrade to a newer release, disable respective features, remove the
product or replace the product by another one.
