accepts integer values and represents the `User ID' of users in the
web site. For example: http://www.example.com/?author=1

Vulnerability Insight:
The problems found are:

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:
These problems trigger the following attack vectors:

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.

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.
