[SOUND] All right, so this is a little hint video if you weren't able to solve and patch the code in WebGoat. You don't have to remember this URL. This is stormpath.com and there's a great post by Lindsay Bronner. And where it explains JWT, and specifically gives examples of how to go about patching this. So if you weren't able to identify the vulnerability and where the code is incorrect inWebGoat, gives this a look. The URL to this will be in your course notes. And give it a try and see if you're able to solve the problem and patch the code given this example.
