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.

  • Revert API defaults for issuer reference kind and group introduced in 0.19.0 (#​8178, @​cert-manager-bot)

v1.18.3

Compare Source

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

We fixed a bug which caused certificates to be re-issued unexpectedly, if the issuerRef kind or group was changed to one of the "runtime" default values. We increased the size limit when parsing PEM certificate chains to handle leaf certificates with large numbers of DNS named or other identities. We upgraded Go to 1.24.9 to fix various non-critical security vulnerabilities.
