A privilege mismatch vulnerability in Fleet allows unauthorized modification of namespace labels and annotations during bundle deployments, bypassing the intended authorization checks. This could lead to unauthorized changes in namespace metadata, potentially impacting the security and integrity of the deployment environment. Organizations using affected versions of SUSE Rancher Fleet should prioritize remediation to mitigate the risk of privilege escalation and unauthorized access.

Original NVD Description

A privilege mismatch was found in Fleet. When a bundle requested namespace labels or annotations through the namespaceLabels and namespaceAnnotations options, the resulting namespace metadata update was not subject to the same authorization as the rest of the bundle's deployment. As a result, a bundle could change labels and annotations on a target namespace even when the identity it was pinned to was not authorized to modify that namespace. This affected SUSE Rancher Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, 0.14 before 0.14.11, 0.13 before 0.13.16 and potentially older versions.
