The remote web server contains a PHP application that is affected by a
cross-site scripting vulnerability.
The version of WordPress installed on the remote host fails to
properly sanitize input to the 'Host' request header before using it
in the 'self_link()' function in 'wp-includes/feed.php' to generate
dynamic HTML output. An attacker can leverage this issue to inject
arbitrary HTML and script code into a user's browser to be executed
within the security context of the affected site.
