build(deps): bump the golang group across 1 directory with 4 updates

[dependabot]

Bumps the golang group with 1 update in the / directory: github.com/cert-manager/cert-manager.

Updates github.com/cert-manager/cert-manager from 1.20.3 to 1.21.1

Release notes

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

v1.21.1

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

v1.21.1 fixes a controller panic for Certificates with spec.renewal.policy: Disabled, a regression in 1.21.0 which caused log spam and dropped Secret informer events, Issuers and ClusterIssuers getting stuck at Ready=False (InvalidSolver) when a referenced ACME DNS-01 solver Secret is created after the Issuer, and the commented Gateway API example in the Helm chart values. It also updates several dependencies to fix reported security vulnerabilities.

All users should upgrade.

Changes by Kind

Bug or Regression

• Avoid controller panic if a Certificate sets spec.renewal.policy=Disabled (#9038, @​sklirg)
• Fix Issuer/ClusterIssuer stuck at Ready=False/InvalidSolver after a missing ACME DNS-01 solver Secret is created (#9083, @​SebTardif)
• Fix log spam and dropped Secret informer events for non-cert-manager Secrets, caused by a generics regression introduced in 1.21.0. (#9037, @​wallrj-cyberark)
• Fixed the commented Gateway API config example in the Helm chart values to use gatewayAPI.enabled instead of the invalid gatewayAPI.enable. (#9012, @​mateenali66)

Other (Cleanup or Flake)

• Bump golang.org/x/text to v0.40.0 to fix a reported security vulnerability (#9039, @​wallrj-cyberark)
• Bump google.golang.org/grpc to v1.82.1 to fix a reported security vulnerability (#9063)
• Bump github.com/google/cel-go to v0.29.0 to fix a reported security vulnerability (#9072)
• Bump go.opentelemetry.io/otel to v1.44.0 to fix a reported security vulnerability (#9073)
• Update distroless base images (#9000, #9025)

v1.21.0

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

cert-manager 1.21 brings ACME Renewal Information (ARI) support, AWS IAM authentication for the Vault issuer, several security hardening changes, and continued improvements to Gateway API integration and cainjector. There are three breaking changes related to Helm chart RBAC and metrics values — review them carefully before upgrading.

Known Issues

• Controller crash-loops when a Certificate sets renewal.policy: Disabled: the new Certificate renewal policies feature (#8258) causes a nil pointer dereference panic in the trigger controller whenever a Certificate's spec.renewal.policy is set to Disabled — pki.RenewalTime() returns (nil, nil) for that policy, but the caller unconditionally dereferences the result. This crashes the controller process (crash-loop) for any cluster with such a Certificate. Workaround: do not set renewal.policy: Disabled on any Certificate until this is fixed; remove the field (or set a different policy) from any Certificate that already has it, and restart the controller if it is currently crash-looping. See #9031 for details.
• Log spam for non-cert-manager-labelled Secret events: the typed predicates refactoring (#8407) causes filteredEventHandler type assertion failures ("OnAdd missing Object", "OnUpdate missing ObjectOld", "OnDelete missing Object") for every non-cert-manager-labelled Secret event, multiplied by 7 certificate sub-controllers. This is cosmetic only — the affected controllers only need events from cert-manager-labelled Secrets (which arrive via the typed informer); the metadata informer events were always filtered out by predicates in previous versions. Issuer and ClusterIssuer controllers are not affected. See #8994 for details.
• Issuer/ClusterIssuer can get stuck at Ready: False, Reason: InvalidSolver and never self-correct: new eager validation of ACME solver Secrets (#8255) means an Issuer/ClusterIssuer referencing a solver Secret (e.g. a DNS01 provider credential) that doesn't exist yet will correctly report Ready: False, but creating the missing Secret afterwards does not trigger re-reconciliation — the controller's Secret-watch logic was never updated to recognise solver Secrets. It will only recover on the next 10-hour informer resync, a change to the Issuer/ClusterIssuer's own spec, or a controller restart. Workaround: after creating the missing Secret, make a trivial edit to the Issuer/ClusterIssuer spec (or delete and recreate it) to force reconciliation. See cert-manager/cert-manager#9036 for details and a fix proposal.

Major Themes

Default tokenrequest RBAC removed from Helm chart

⚠️ Breaking change

The Helm chart no longer creates a default Role and RoleBinding granting the cert-manager controller permission to create tokens for its own ServiceAccount (serviceaccounts/token: create). No documented workflow requires this RBAC — the Route53 docs section that motivated it was removed in 2024.

If you use serviceAccountRef.name pointing at the controller ServiceAccount, you must now either create your own Role/RoleBinding granting serviceaccounts/token: create, or migrate to a dedicated ServiceAccount (recommended — see the Vault or Route53 documentation).

Restrict Challenge and Order RBAC in cert-manager-edit ClusterRole

⚠️ 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 (GHSA-8rvj-mm4h-c258). These resources are internal to cert-manager's ACME workflow. Challenge patch and update are retained because users may need them to remove stuck finalizers.
