Unfortunately do to an unforeseen oversight, a change needs to be made to a security fix to those of you who applied the patch before this post (October 29th, 2008).

ONLY If you applied or downloaded the MyBB 1.4.3 Package before October 29th, 2008.

Quote:In inc/functions.php find:
echo "alert('".str_replace("'", "\'", $message)."');\n";

and replace with

echo 'alert("'.addslashes($message).'");';

echo "window.location = '".str_replace("'", "\'", $url)."';\n";

and replace with

echo 'window.location = "'.addslashes($url).'";'."\n";

As of the time of this post the changed file package, manual file changes, and the MyBB download have been updated. We apologize for any inconvenience this may have caused you.
