Researchers today disclosed multiple data leaks resulting from Microsoft Power Apps portals configured to allow public access – a new vector of data exposure. The types of data varied between portals, including personal information used for COVID-19 contact tracing, COVID-19 vaccination appointments, social security numbers for job applicants, employee IDs, and millions of names and email addresses. UpGuard notified 47 entities of exposures involving personal information, including governmental bodies like Indiana, Maryland, and New York City, and private companies like American Airlines, J.B. Hunt, and Microsoft, for a total of 38 million records across all portals. This research presents an example of a larger theme, which is how to manage third-party risks (and exposures) posed by platforms that don’t slot neatly into vulnerability disclosure programs as we know them today, but still present as security issues.
