People have told you what they are, good. IMHO however you are much better off resetting %ENV. Kill it, %ENV = ();. This way you know for sure you aren't passing anything bad. Or at the very least, explicitly pass only things you know are safe or you have sanitized. 
my @PATH = ($ENV{PATH} =~ m/clean/);
%ENV = (
        PATH => join(':', @PATH);
        );
