A major security flaw in a software solution exposed private information of restaurant customers. Data collected for coronavirus contact tracking forms have also been affected. The Chaos Computer Club, a European association of hackers, found that the vulnerability in the Cloud software system left over 4 million data entries from the past nine years accessible to hackers.

Gastronovi, the software company, said to BR and NDR that the flaws in their security system have now been plugged — but that the responsibility for data sovereignty was "exclusively up to our customers." Restaurants who make use of the service are supposed to delete the data entries themselves.
