v1.20.3Security

2026年6月26日リンクをコピー

v1.20.3 is a security release primarily addressing a HIGH-severity RBAC over-permission (GHSA-8rvj-mm4h-c258) in the cert-manager-edit ClusterRole, and updating Go to v1.26.4 for three CVEs. Operators should audit any workflows that create Challenge or Order resources directly before upgrading, as those permissions are now removed.

• securityRBAC over-permission in cert-manager-edit ClusterRole (GHSA-8rvj-mm4h-c258)

  GHSA-8rvj-mm4h-c258 (HIGH): the cert-manager-edit aggregate ClusterRole previously allowed namespace users to create Challenge and Order resources directly, bypassing Issuer solver selectors. Fixed in v1.20.3. Upgrade immediately if untrusted namespace users exist in your cluster.

• breakingBreaking RBAC change: direct Challenge and Order creation removed from cert-manager-edit

  cert-manager-edit no longer grants create on challenges.acme.cert-manager.io, or create/patch/update on orders.acme.cert-manager.io. If any tooling or CI workflow creates Challenge or Order objects directly (outside the normal Certificate → CertificateRequest → Order → Challenge flow), those calls will fail after upgrading. Review and update any such automation before rolling out v1.20.3.

• securityGo runtime updated to v1.26.4 (3 CVEs)

  Go updated to v1.26.4, patching CVE-2026-27145, CVE-2026-42504, and CVE-2026-42507. No additional configuration is required; upgrading cert-manager picks up the fix.
