Millions of individuals and businesses registered on Companies House have been warned following the discovery of a significant website glitch that potentially exposed personal data. The issue allowed authorized users logged into the system to view and edit details belonging to other companies, including sensitive information such as directors’ home addresses and email addresses, without permission. Andy King, CEO of Companies House since September, publicly apologized for the incident after being informed of the security lapse last Friday.
