CVE-2026-44938Suse Rancher Fleet Insufficiently Protected Credentials

NVDCVSS scored by meissner@suse.de

Vulnerability Summary

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.
