Even if WP.org is safely doing the right thing, this is a security
issue that needs to be fixed. It's unsanitized data from a third party

Okay, so spoofing the DNS to redirect what "wordpress.org" means to
the webserver would be a bit of a long way to go to hack a website,
but it can still be done.
