If your thinking of using a script/application on your website and want to know or want to check to find out if it has any current risks or problems, we would recommend going to secunia.com
You can use secunia.com to identify any known risks or security flaws in your application, then contact your script/application developers to ensure the problem is eliminated (If they are not already aware of it)
You may however find that secunia.com only list's all of the popular applications and/or scripts and some of the smaller applications and scripts may not be listed if nobody is finding or reporting anything about them.
