And a solution for first bug (XSS):


File: functions.php, function redirect()

FIND:
----------------
function redirect($url, $message="", $title="")
{
global $header, $footer, $mybb, $theme, $headerinclude, $templates, $lang, 
$plugins;

$redirect_args = array(’url’ => &$url, ‘message’ => &$message, ‘title’ => 
&$title);

$plugins->run_hooks_by_ref(”redirect”, $redirect_args);

if($mybb->input['ajax'])
----------------
REPLACE WITH:
----------------
function redirect($url, $message="", $title="")
{
global $header, $footer, $mybb, $theme, $headerinclude, $templates, $lang, 
$plugins;

$redirect_args = array(’url’ => &$url, ‘message’ => &$message, ‘title’ => 
&$title);

$plugins->run_hooks_by_ref(”redirect”, $redirect_args);

$url = addslashes($url) ;
if($mybb->input['ajax'])
----------------
