This way you can sell and have the ticket completely off of ticketmaster. That is a vulnerability. It lets users do something they explicitly don't want to allow.

Assuming that you can actually do that.

If the seller re-opens the TM app and it generates a new token and invalidates the old one, then that's not the case.

Vulnerability to LN business practices. Not a system vulnerability.
