Package Update Change
cert-manager (source) minor v1.17.1 → v1.20.3

Release Notes

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

v1.20.3

Compare Source

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

This patch release fixes a security issue (GHSA-8rvj-mm4h-c258, HIGH) where the default cert-manager-edit aggregate ClusterRole granted namespace users permission to create ACME Challenge and Order resources directly. A user who could create a Challenge referencing a ClusterIssuer could supply attacker-controlled solver configuration while cert-manager loaded credentials from the ClusterIssuer's namespace, bypassing Issuer solver selectors (dnsZones, dnsNames, matchLabels). With the acme-dns provider specifically, this could disclose DNS credentials to an attacker-controlled endpoint.

This release also removes the issuer owner reference from Challenges which was blocking Challenge garbage collection, and updates Go to fix reported CVEs.

All users should upgrade.

[!WARNING]
Potentially breaking change: The cert-manager-edit aggregate ClusterRole no longer grants create for challenges.acme.cert-manager.io or create, patch, update for orders.acme.cert-manager.io. These resources are internal to cert-manager's ACME workflow and are not intended to be created or modified directly by users. If you have tooling or workflows that create Challenge or Order resources directly (outside of the normal Certificate → CertificateRequest → Order → Challenge flow), you will need to grant those permissions explicitly.

v1.20.2

Compare Source

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

v1.20.2 fixes invalid YAML generated in the Helm chart when both webhook.config
and webhook.volumes are defined, and bumps Go to 1.26.2 along with dependencies
to address reported vulnerabilities.

v1.20.1

Compare Source

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

v1.20.1 fixes an issue for OpenShift users that has to do with the finalizer RBAC, bumps gRPC to address a reported non-affecting vulnerability, and fixes a duplicate parentRef bug when both issuer config and annotations are present (Gateway API).

Bug or Regression
  • Fixed duplicate parentRef bug when both issuer config and annotations are present. (#​8658, @​hjoshi123)
  • Add missing issuer finalizer RBAC to the order controller to support owner references. This was preventing OpenShift users from being able to upgrade to v1.20.0. (#​8655, @​erikgb)
  • Bump google.golang.org/grpc to fix vulnerability reported by scanners. This isn't a vulnerability that affects cert-manager, but we are bumping it because it is reported by scanners. (#​8657, @​erikgb)

v1.20.0

Compare Source

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

v1.20.0 adds alpha support for the new ListenerSet resource, adds support for Azure Private DNS; parentRefs are no longer required when using ACME with Gateway API, and OtherNames was promoted to Beta.

Changes by Kind

Feature
  • Added a set of flags to permit setting NetworkPolicy across all deployed containers. Remove redundant global IP ranges from example policies. (#​8370, @​jcpunk)
  • Added selectable fields to custom resource definitions for .spec.issuerRef.{group, kind, name} (#​8256, @​tareksha)
  • Added support for specifying imagePullSecrets in the startupapicheck-job Helm template to enable pulling images from private registries. (#​8186, @​mathieu-clnk)
  • Added 'extraContainers' helm chart value, allowing the deployment of arbitrary sidecar containers within the cert-manager operator pod. This can be used to support, for e.g., AWS IAM Roles Anywhere for Route53 DNS01 verification. (#​8355, @​dancmeyers)
  • Added parentRef override annotations on the Certificate resource. (#​8518, @​hjoshi123)
  • Added support for azure private zones for dns01 issuer. (#​8494, @​hjoshi123)
  • Added support for configuring PEM decoding size limits, allowing operators to handle larger certificates and keys. (#​7642, @​robertlestak)
  • Added support for unhealthyPodEvictionPolicy in PodDisruptionBudget (#​7728, @​jcpunk)
  • For Venafi provider, read venafi.cert-manager.io/custom-fields annotation on Issuer/ClusterIssuer and use it as base with override/append capabilities on Certificate level. (#​8301, @​k0da)
  • Improve error message when CA issuers are misconfigured to use a clashing secret name (#​8374, @​majiayu000)
  • Introduce a new Ingress annotation acme.cert-manager.io/http01-ingress-ingressclassname to override http01.ingress.ingressClassName field in HTTP-01 challenge solvers. (#​8244, @​lunarwhite)
  • Update global.nodeSelector to helm chart to perform a merge and allow for a single nodeSelector to be set across all services. (#​8195, @​StingRayZA)
  • Vault issuers will now include the Vault server address as one of the default audiences on generated service account tokens. (#​8228, @​terinjokes)
  • Added experimental XListenerSets feature gate (#​8394, @​hjoshi123)
Documentation
Bug or Regression
  • Adds logs for cases when acme server returns us a fatal error in the order controller (#​8199, @​Peac36)
  • Fixed an issue where kind or group in the issuerRef of a Certificate was omitted, upgrading to 1.19.x incorrectly caused the certificate to be renewed (#​8160, @​inteon)
  • Changes to the Duration and RenewBefore annotations on ingress and gateway-api resources will now trigger certificate updates. (#​8232, @​eleanor-merry)
  • Fix an issue where ACME challenge TXT records are not cleaned up when there are many resource records in CloudDNS. (#​8456, @​tkna)
  • Fix unregulated retries with the DigitalOcean DNS-01 solver
    Add full detailed DNS-01 errors to the events attached to the Challenge, for easier debugging (#​8221, @​wallrj-cyberark)
  • 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. (#​8403, @​calm329)
  • Fixed an issue where HTTP-01 challenges failed when the Host header contains an IPv6 address. This means that users can now issue IP address certificates for IPv6 address subjects. (#​8424, @​SlashNephy)
  • Fixed the HTTP-01 Gateway solver creating invalid HTTPRoutes by not setting spec.hostnames when the challenge DNSName is an IP address. (#​8443, @​alviss7)
  • Revert API defaults for issuer reference kind and group introduced in 0.19.0 (#​8173, @​erikgb)
  • 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. (#​8469, @​SgtCoDFish)
  • Update Go to v1.25.5 to fix CVE-2025-61727 and CVE-2025-61729 (#​8290, @​octo-sts[bot])
  • When Prometheus monitoring is enabled, the metrics label is now set to the intended value of cert-manager. Previously, it was set depending on various factors (namespace cert-manager is installed in and/or Helm release name). (#​8162, @​LiquidPL)
Other (Cleanup or Flake)

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.

v1.18.6 is a simple patch release to fix some reported vulnerabilities, most notably CVE-2025-68121.

NB: We didn't attempt to patch CVE-2026-24051 but that vulnerability affects macOS only, so cert-manager will be unaffected.
