Release Notes

cert-manager/cert-manager (cert-manager)

v1.19.1

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

We reverted the CRD-based API defaults for Certificate.Spec.IssuerRef and CertificateRequest.Spec.IssuerRef after they were found to cause unexpected certificate renewals after upgrading to 1.19.0. We will try re-introducing these API defaults in cert-manager 1.20. We fixed a bug that caused certificates to be re-issued unexpectedly if the issuerRef kind or group was changed to one of the "runtime" default values. We upgraded Go to 1.25.3 to address the following security vulnerabilities: CVE-2025-61724, CVE-2025-58187, CVE-2025-47912, CVE-2025-58183, CVE-2025-61723, CVE-2025-58186, CVE-2025-58185, CVE-2025-58188, and CVE-2025-61725.

Changes since v1.19.0:

Bug or Regression
  • BUGFIX: in case kind or group in the issuerRef of a Certificate was omitted, upgrading to 1.19.x incorrectly caused the certificate to be renewed (#​8175, @​cert-manager-bot)
  • Bump Go to 1.25.3 to fix a backwards incompatible change to the validation of DNS names in X.509 SAN fields which prevented the use of DNS names with a trailing dot (#​8177, @​wallrj-cyberark)
  • Revert API defaults for issuer reference kind and group introduced in 0.19.0 (#​8178, @​cert-manager-bot)
