AI Summary

Krajowa Izba Rozliczeniowa S.A. (KIR) faced an issue where a certificate was issued with a Common Name (CN) that was not included in the Subject Alternative Name (SAN) field. The problem was identified shortly after issuance, leading to an investigation and subsequent revocation of the certificate. KIR acknowledged the lack of technical validation in their software as a contributing factor and has since updated their SSL certificate issuance procedures to prevent similar issues in the future.
