CVE-2026-44938Network attack vector

Admission-control bypass via unfiltered namespace labels

Published Jul 7, 2026 · Updated Jul 7, 2026

Authorization bypass in Fleet for SUSE Rancher allows remote authenticated users to weaken Kubernetes namespace admission controls. The agent-side addLabelsFromOptions path applied namespaceLabels from fleet.yaml or BundleDeployment options without rejecting pod-security.kubernetes.io keys. Git push access to a monitored repository is required; successful abuse permits workloads that the cluster PSS policy would reject.
