Hi Johanna,

of course it's a vulnerability.

What it comes to my mind is that It depends if they consider credit card
processing in scope or not. I explain better many times credit cards are
handled by external companies that have also to validate the credit card
before processing a transaction. In case the external company could even
be charged for the issue.

On the other hand bug bounties have guidelines and only specific issues
are rewarded. Unfortunately is part of the game, and I personally do not
like much bug bounties.
