The door to your personal data got left wide open once again.

Researchers revealed Tuesday that earlier this year they discovered a massive database -- containing information on more than 123 million American households -- that was sitting unsecured on the internet.

The cloud-based data repository from marketing analytics company Alteryx exposed a wide range of personal details about virtually every American household, according to researchers at cybersecurity company UpGuard. The leak put consumers at risk for a range of nefarious activities, from spamming to identity theft, the researchers warned.

Though no names were exposed, the data set included 248 different data fields covering a wide variety of specific personal information, including address, age, gender, education, occupation and marital status. Other fields included mortgage and financial information, phone numbers and the number of children in the household.

"From home addresses and contact information, to mortgage ownership and financial histories, to very specific analysis of purchasing behavior, the exposed data constitutes a remarkably invasive glimpse into the lives of American consumers," UpGuard researchers Chris Vickery and Dan O'Sullivan wrote in their analysis.

Experian added a pass-the-buck aspect to its response: "This is an Alteryx issue, and does not involve any Experian systems. Alteryx has already confirmed with you that the data in question contained no names of any individuals or any other personal identifying information, and does not pose any risk of identity theft to any consumers. We have been assured by Alteryx that they promptly remedied this issue."
