Beyond the rows above, the remaining scanner findings in this batch were cleared by the same module and toolchain bumps: the Go toolchain (1.26.3 → 1.26.7), golang.org/x/crypto (0.50.0 → 0.55.0), go-git, fulcio, rekor, golang.org/x/mod, google.golang.org/grpc (1.80.0 → 1.83.2), and oras.land/oras-go/v2 (2.6.0 → 2.6.2). All findings were Go standard library or Go module issues; the Wolfi runtime base image was not affected.
Fixes
- Stopped a reports-server watcher leak that caused an out-of-memory cascade.
- Inferred a
Namespacedwebhook scope for namespace-constrained wildcard policies, and backported the related namespaced-policy fixes. - Handled missing reports CRDs as a no-op in
kyverno-initso initialization no longer fails when the reports CRDs are absent. - Granted
watchon deleting policies to the licensing informers so the live policy counter stays in sync. - Pointed the webhooks-cleanup readiness checker at the Nirmata image.
Additional changes
- Added the
--apiCallBlocklistand--apiCallAllowlistflags (settable through Helm values) to control which destinationscontext.apiCall.servicemay reach; these are separate from the CEL--httpBlocklist/--httpAllowlistflags, so in-cluster ClusterIP calls keep working by default. - Extended conformance coverage to Kubernetes 1.36 and 1.37.
- Fixed the FIPS image builds: stopped shipping the whole build context, bumped the
kubectl-kyvernoFIPS builder to Go 1.26.7, and mounted the private-module secret in thekubectl-kyvernoFIPS build.
v1.18.0-n4k.nirmata.2 — August 17, 2026
Licensing
- Added a free community tier so open-source use runs without a commercial license.
- Enforced commercial licensing for policy capacity and commercial features.
- Set the license evaluation interval to 15 minutes.
- Included licensing fixes for enterprise deployments.
