I think you are confused by the variable $CMD which is not the CMD line.

Maybe this looks better to you:

sub get_response {
  my ($cgi, $query) = shift;
 
  $ENV{QUERY_STRING} = $query;
  $ENV{REQUEST_METHOD} = 'GET';
  $ENV{GATEWAY_INTERFACE} = 'CGI/1.1';

  open(CGI, '-|', $cgi) or die "Can't exec $cgi, $!";
  local $/ = undef;
  my $res = <CGI>;
  close(CGI) or die "Error running $cgi, $!";
  return $res;
}

Note: I used the 3 argument form of open as it is generally safer to use.
