Vulnerability details
CVE-2026-44938
SUSE Rancher
Fleet has PSS Bypass through addLabelsFromOptions in Fleet Agent
CVSS 3.1
8.8High
Official description
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.
