DESCRIPTION:
David Kierznowski has discovered a vulnerability in WordPress, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "file" parameter in wp-admin/templates.php is not
properly sanitised before being stored. This can be exploited to
insert arbitrary HTML and script code, which will be executed in an
administrative user's browser session in context of an affected site
when the templates.php script is accessed.

Successful exploitation requires that the target user is logged in
with administrator privileges.

The vulnerability is confirmed in version 2.0.5. Other versions may
also be affected.

SOLUTION:
Apply the vendor's official fix:
