I bruteforce a password for your JWT-enabled app. Then I have a token. Copy the token from my browser ( usually just open Network tab at the inspector and copy the headers for the request ). Then I store the token at my server and make it execute a request to the app on intervals to prevent from expiring ( reissue ) the token. How can you invalidate my server now?
