Jeremias Reith has reported a vulnerability in WordPress, which can
be exploited by malicious people to conduct script insertion
attacks.

Input passed via the HTTP "Host" header is not properly sanitised
before being used. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site if malicious data is viewed.

on Apache 2.x.
