Apparently insecure use of wildcards

[LVSant]

Our research team at Tenchi found some apparently insecure use of wildcards (*) in your Custom Lambda Authorizer. Precisely here. When you use wildcards anywhere in policies resources other than in the very end and after a slash, you're very likely to be allowing your users to access more API endpoints than you intended. This is because the wildcard (*) doesn't stop expanding at slashes (/), as the AWS documentation stated up until very recently.
