[dependabot]

Bumps github.com/cert-manager/cert-manager from 1.9.1 to 1.18.0.

Release notes

Sourced from github.com/cert-manager/cert-manager's releases.

v1.18.0

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

cert-manager 1.18 introduces several new features and breaking changes. Highlights include support for ACME certificate profiles, a new default for Certificate.Spec.PrivateKey.RotationPolicy now set to Always (breaking change), and the default Certificate.Spec.RevisionHistoryLimit now set to 1 (potentially breaking).

ℹ️ Be sure to review all new features and changes below, and read the full release notes carefully before upgrading.

Known Issues

• ACME + HTTP01 + Ingress-Nginx: Error presenting challenge: admission webhook "validate.nginx.ingress.kubernetes.io" denied the request: ingress contains invalid paths: path /.well-known/acme-challenge/<REDACTED> cannot be used with pathType Exact (#7791)

Changes since v1.17.2:

Feature

• Add config to the Vault issuer to allow the server-name to be specified when validating the certificates the Vault server presents. (#7663, @​ThatsMrTalbot)

• Allow customizing signature algorithm (#7591, @​tareksha)
• Cache the full DNS response and handle TTL expiration in FindZoneByFqdn (#7596, @​ThatsIvan)

• Add support for ACME profiles extension. (#7777, @​wallrj)
• Promote the UseDomainQualifiedFinalizer feature to GA. (#7735, @​jsoref)
• Switched service/servicemon definitions to use port names instead of numbers. (#7727, @​jcpunk)
• The default value of Certificate.Spec.PrivateKey.RotationPolicy changed from Never to Always. (#7723, @​wallrj)
• Potentially breaking: Set the default revisionHistoryLimit to 1 for the CertificateRequest revisions (#7758, @​ali-hamza-noor)

Documentation

• Fix some comments (#7620, @​teslaedison)

Bug or Regression

• Bump go-jose dependency to address CVE-2025-27144. (#7606, @​SgtCoDFish)

• Bump github.com/golang-jwt/jwt to patch GHSA-mh63-6h87-95cp. (#7638, @​NicholasBlaskey)

• Fix AWS Route53 error detection for not-found errors during deletion of DNS records. (#7690, @​wallrj)
• Fix behavior when running with --namespace=<namespace>: limit the scope of cert-manager to a single namespace and disable cluster-scoped controllers. (#7678, @​tsaarni)
• Fix handling of certificates with IP addresses in the commonName field; IP addresses are no longer added to the DNS subjectAlternativeName list and are instead added to the ipAddresses field as expected. (#7081, @​johnjcool)
• Fix issuing of certificates via DNS01 challenges on Cloudflare after a breaking change to the Cloudflare API (#7549, @​LukeCarrier)
• Fixed the certmanager_certificate_renewal_timestamp_seconds metric help text indicating that the metric is relative to expiration time, rather than Unix epoch time. (#7609, @​solidDoWant)
• Fixing the service account template to incorporate boolean values for the annotations. (#7698, @​ali-hamza-noor)
• Quote nodeSelector values in Helm Chart (#7579, @​tobiasbp)
