[ submit.php line 27 ]
 
$user_count = $wpdb->get_var("SELECT COUNT(*) FROM $table_email where email ='$_POST[email_add]' and id_lista = '$_POST[lista]';");
 
 
As you can see, $_POST[lista] parameter is nor validated neither escaped, so you can blind sql inject it using $user_count for the
boolean condition checking :
 
 
[ submit.php line 29 ]
 
if($user_count>0) :
  $errore_presente = "<div class=\"error\">".__('email address already present', 'sendit')."</div>";
  die($errore_presente);

lista = BLIND SQL INJECTION HERE
