CVE-2026-10079Network attack vector

Policy enforcement bypass via null deployment metadata

Published Jul 31, 2026 · Updated Jul 31, 2026

Metadata verification failure in RHACS 4 allows remote authenticated users to evade deploy-time policy enforcement through a crafted label. The Deployment converter JSON-unmarshals the openshift.io/encoded-deployment-config label and accepts null as replacement identity metadata. Permission to create Kubernetes Deployments is required; the null identity hides violations, prevents Central persistence, and corrupts reporting for that workload.
