I upgraded to WordPress 2.8.2 which fixes an XSS vulnerability. Comment author URLs were not fully sanitized when displayed in the admin. This could be exploited to redirect from the admin to another site.

I’ve upgraded this chess tutorials site to WordPress 2.8.1.
So far I didn’t experience problems, but I’m keeping my fingers crossed.
