`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.
