Yes, exist multiple XSS vulnerabilities described in the CVE-2013-5943
[1]. Some XSS were fixed but other not (I found a persistent XSS [2]).
Any user identified in the application could inject javascript code that
could be executed in the victim. Is not possible get the cookie in
javascript because has the "HTTPOnly" flag.

Yes, both are vulnerable to CSRF (and all the edit graphs are vulnerable
too, deleted included).
