Description
A vulnerability has been identified in Rancher's 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.
* Write to /var/lib/rancher/ to tamper with cluster state.
* If hostPath volumes are mounted, write to the host node filesystem.
* Use this issue to chain with other attack vectors.
