PHP code execution and local file disclosure as well as SQL injection
attacks.");

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

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