CVE-2026-44938

Fleet has PSS Bypass through addLabelsFromOptions in Fleet Agent

A vulnerability has been identified in Fleet's agent-side deployer, which did not filter security-sensitive keys from namespaceLabels in fleet.yaml (or BundleDeployment.spec.options.namespaceLabels) when applying them to the target namespace.




An attacker with git push access to a
 Fleet-monitored repository could overwrite Pod Security Standards (PSS)
 enforcement labels on a target namespace. This allows the attacker to 
weaken admission controls and deploy workloads that PSS policies would 
otherwise block.
