Bugzilla #1531817 Certificate Misissuance

DigiCert: in-addr.arpa Misissuance

RESOLVED DigiCert
AI Summary

DigiCert experienced a misissuance of certificates for the in-addr.arpa domain due to improper validation processes. A validation agent incorrectly set the scope of domain control validation, allowing certificates to be issued for domains that the requester did not control. Following the incident, DigiCert revoked the misissued certificates and implemented changes to their validation procedures to prevent similar occurrences in the future.
