"According to its self-reported version number, the WordPress application running on the remote web server is prior to
2.0.2. It is, therefore, affected by multiple cross-site scripting (XSS) vulnerabilities due to improper validation of
user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit this, by convincing a
user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

Note the vulnerabilities fixed in this release were reported to and addressed by the WordPress development team without
disclosure. For more information see the linked security advisory");
