This vulnerability allows a user with specific permissions to manipulate how the system handles sensitive information, known as Secrets, across different parts of the system (namespaces). By exploiting this, an attacker can modify these Secrets in unauthorized areas. This could lead to unauthorized access to information or elevated privileges within the system.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:60387** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.11 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60387)\n- **RHSA-2026:60390** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.13 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60390)\n- **RHSA-2026:60388** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.14 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60388)\n- **RHSA-2026:60389** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.15 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60389)\n- **RHSA-2026:60391** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.16 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60391)\n- **RHSA-2026:60386** · Red Hat · fixed in: Red Hat Advanced Cluster Management for Kubernetes 2.17 · released 2026-08-26 · [advisory](https://access.redhat.com/errata/RHSA-2026:60386)","depth":"sunlit","depthScore":35,"depthScoreParts":{"impact":35.2,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
