The BBC story at the link below discusses vulnerabilities on Forums run on vBulletin. While that shouldn't bother this site running on phpBB, the US Large Format site uses vBulletin and therefore might be vulnerable at the moment.

The US LF site is safe. It's running version 3.6.4. The version with the problem is 3.8.6.

Best to let others upgrade first to test the release
