A seldom known page on Comcast’s Xfinity website was exposing customers’ account information to anyone — or any app — on a customer’s network.
The API was used as part of the Xfinity’s website to help customers find stores and get account information. Because the API only returns data when it recognizes an Xfinity customer’s IP address, accessing a line owner’s customer data requires someone to already be on a customer’s network.
“There’s nothing more important than our customers’ privacy and security,” said a spokesperson. “As soon as we became aware of this situation, our engineers turned the feature off, which could only be accessed within a customer’s home or while logged into the customer’s Wi-Fi network.”
“We have no reason to believe that anyone’s account information was improperly taken or used,” said the spokesperson, citing no evidence.
It’s the second Xfinity security issue in as many months.
