DigiCert archived customer validation records read by a self-registered account

DigiCert disclosed in a Mozilla Bugzilla incident report on October 21, 2026 that an internal business system archiving information customers provide to validate their identity had been reachable from the internet since a February 4, 2025 migration, and that an account-registration feature let outsiders create accounts on it. Those accounts were not subject to the MFA DigiCert otherwise requires and, through a missing authorization check, could read archived data; one account did so between June 27 and July 2, 2026, which DigiCert confirmed on October 19. The data was mostly business contact details, with driver's licences, passports or utility bills for a minority of customers; certificate issuance was not affected.

The identity lesson

Anyone could register an account, and a default read-only role still reached customer identity documents. Turning off self-registration on internal systems, MFA on every account path, and authorization that denies data access to accounts with no assigned role are the controls.
