  "details": "A vulnerability has been identified in [Rancher's Extensions](https://ranchermanager.docs.rancher.com/integrations-in-rancher/rancher-extensions) where malicious code can be injected in Rancher through a path traversal in the `compressedEndpoint` field inside a `UIPlugin` deployment. 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.",
