[ISSUE]

WPkontakt is the another Polish instant messenger. The problem is similiar
to the problems revealed in GG or Tlen.pl - parsing error leading to the
remote script execution.


[DETAILS]

Parsing error while parsing en email addresses allows us to inject
javascript code like this:

test@"style="background-image:url(javascript:alert(%22You%20are%20owned!%22>))".wp.pl

The code will execute in Internet Zone.


[SOLUTION]

Please upgrade to the newest version (3.0.1p1)
