We have found uncritical sql injection vulnerability in com_contents

  101                     recordVote ( $url , $user_rating , $cid ,  
$database);
  102                     break;
  ...
  1478                                    $query = "UPDATE  
#__content_rating"
  1479                                    . "\n SET rating_count =  
rating_count + 1,"
  1450                                    . "\n rating_sum = rating_sum  
+ $user_rating,"
  1451                                    . "\n lastip = '$currip'"
  1452                                    . "\n WHERE content_id = ". $cid
  1453                                    ;
