An unprotected CitySourced database, owned by Granicus, exposed approximately 42 million civic records.

The lesson from this incident

Full lesson

CitySourced, operated by Granicus, left a database containing approximately 42 million civic records publicly accessible without password protection or encryption — a fundamental configuration failure. This exposed sensitive personal information including names, addresses, and phone numbers of residents who had interacted with government complaint and code violation systems. The breach highlights that organizations handling civic data must apply the same rigorous security baseline to every data store, not just high-profile systems. When a vendor or SaaS provider manages government data, any misconfiguration becomes a public trust issue with significant regulatory implications.
