Thread:Extension talk:WYSIWYG/About security issues with wysiwyg

Older FCKeditor was told to have all kind of security issues.

I am not an expert on this field so I am wondering...
 * 1) How safe it would be to use wysiwyg as editor in wiki which is open to internet?
 * 2) If underlying CKeditor is safe, is it possible that modifications of mediawiki (wikitext-wysiwyg) have somehow compromised this securiry?
