CVE-2026-44938
CWE-522Published: July 7, 2026· Updated: Jul 8, 2026
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.
Technical Analysis
CVE-2026-44938 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
