CVE-2026-93540: CWE-266 Incorrect privilege assignment in SUSE Rancher
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.
AI Analysis
Technical Summary
A privilege mismatch was identified in SUSE Rancher Fleet where bundles requesting namespace labels or annotations via namespaceLabels and namespaceAnnotations options could update namespace metadata without undergoing the same authorization as other deployment actions. This flaw enables a bundle to change labels and annotations on a target namespace even if the identity it is pinned to lacks authorization to modify that namespace. The vulnerability affects SUSE Rancher Fleet versions 0.13 before 0.13.16, 0.14 before 0.14.11, 0.15 before 0.15.7, and 0.16 before 0.16.1.
Potential Impact
An attacker controlling a bundle could modify labels and annotations on namespaces they are not authorized to change, potentially impacting namespace metadata integrity. The CVSS score of 6.5 (medium severity) reflects that the vulnerability requires network access with low complexity and low privileges but does not impact confidentiality or availability, only integrity.
Mitigation Recommendations
The vulnerability affects specific versions of SUSE Rancher Fleet prior to 0.13.16, 0.14.11, 0.15.7, and 0.16.1. Users should upgrade to these fixed versions or later to remediate the issue. No vendor advisory or patch links were provided in the input, so verify the current patch status with SUSE's official advisories before taking action.
