Although it isn’t very long after WordPress 2.8.1 was released, WordPress 2.8.2 was just released today and is a security update which corrects a XSS vulnerability which was discovered. Comment author URLs were not fully sanitized when displayed in the admin. This could be exploited to redirect you away from the admin to another site.
Due to this being a security update, it is strongly recommended that you upgrade your WordPress 2.8 installations as soon as possible. This can quickly and easily be done via your WordPress administrator panel (for WordPress 2.7 and newer installations) via Tools –> Upgrade, or you can manually download it here.
If you’d like to read the official announcement, you can see it here.
