Changes by Kind

Bug or Regression

v1.19.3

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

This release contains three bug fixes, including a fix for the MODERATE severity DoS issue in GHSA-gx3x-vq4p-mhhv. All users should upgrade to the latest release.

Changes by Kind

Bug or Regression

  • Fixed an infinite re-issuance loop that could occur when an issuer returns a certificate with a public key that doesn't match the CSR. The issuing controller now validates the certificate before storing it and fails with backoff on mismatch. (#8415, @​cert-manager-bot)
  • Fixed an issue where HTTP-01 challenges failed when the Host header contained an IPv6 address. This means that users can now issue IP address certificates for IPv6 address subjects. (#8436, @​cert-manager-bot)
  • Security (MODERATE): Fix a potential panic in the cert-manager controller when a DNS response in an unexpected order was cached. If an attacker was able to modify DNS responses (or if they controlled the DNS server) it was possible to cause denial of service for the cert-manager controller. (#8468, @​SgtCoDFish)

Other (Cleanup or Flake)

v1.19.2

📖 Read the full 1.19 release notes on the cert-manager.io website before upgrading.

Changes since v1.19.1

Bug or Regression

  • Address false positive vulnerabilities CVE-2025-47914 and CVE-2025-58181 which were reported by Trivy. (#8283, @​SgtCoDFish)
  • Update Go to v1.25.5 to fix CVE-2025-61727 and CVE-2025-61729 (#8294, @​wallrj-cyberark)
  • Update global.nodeSelector to helm chart to perform a merge and allow for a single nodeSelector to be set across all services. (#8233, @​cert-manager-bot)
