Re: ipb Css bug(now public)
While IPB < 1.3 *might* have been vulnerable, IPB 2.x definitely isn't as HTML files are saved with the mime-type "unknown/unknown" which prompts the user to download the file to their desktop making it totally safe.

That may be not true for users using (at least) Internet Explorer, as
"MIME-type sniffing" will be used to determine the file type (and
handler) to use when opening the file.

That's what happen in some Oracle web pages sent with "text/plain" and
vulnerable to a text/code/JS injection. Oracle isn't to blame (really ?)
but the browser (if IE) will execute the JavaScript code.
