CVE-2026-44938: Fleet Agent Deployer NamespaceLabel Injection
CVE-2026-44938 Published on July 7, 2026

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.
