A malicious UI extension could abuse that to: * Overwrite Rancher binaries or configuration to inject code.\n\n * Write to /var/lib/rancher/ to tamper with cluster state.\n\n * If hostPath volumes are mounted, write to the host node filesystem.\n\n * Use this issue to chain with other attack vectors."}], "lastModified": "2026-05-13T15:35:35.267", "sourceIdentifier": "meissner@suse.de"}
