McDonald’s has fallen foul of customer expectations after its McDelivery app leaked the personal information of about 2.2 million users.

Access to the names, emails, home addresses and phone numbers of users was made readily available due to a poorly configured server, according to security firm Fallible.

The fast food giant told the Times of India that the app is safe to use – but Fallible tested the app again after McDonald’s said it had updated it to fix the issue, and found that it was still leaking data.
