cert-manager

v1.21.1Security
Jul 29, 2026

cert-manager v1.21.1 is a patch release fixing controller regressions introduced in 1.21.0: a panic on disabled renewal policy, Issuers stuck at InvalidSolver, and log spam from a generics bug. Helm chart documentation and base image dependencies are also updated.

Key changes (5)

  • Fixes controller panic when Certificate spec.renewal.policy is set to Disabled
  • Fixes Issuer/ClusterIssuer stuck at InvalidSolver when DNS-01 solver Secret is created after the Issuer
  • Fixes log spam and dropped Secret informer events for non-cert-manager Secrets (generics regression from 1.21.0)
  • Helm chart Gateway API config example corrected (gatewayAPI.enabled instead of gatewayAPI.enable)
  • Distroless base images and dependencies updated for security vulnerabilities
