Mastercard Priceless leaks

It looks like customer data of German Mastercard customers (who used the priceless rewards program) has been leaked. I have registered my Curve card with that service as well and my data looks like it has been leaked as well.

Link with more information (german only, unfortunately):

Does anyone know more details about the extent of that leak and if it will be necessary to get a new credit card? I have already locked my Curve card in the app and contacted the support over mail; but maybe someone in this forum has some more information about that situation?
