How big a security threat is this?

Interesting opened this site this morning to find it reveals the DB username, see here:

When trying to contact the Co. via email I get this on the contact form:

"There was a problem capturing your contact details. Perhaps you would like to try again?"

No email addess is supplied in the contact details so gues this is the first report of this.
