CVE-2026-93540 at MITRE

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.
