CVE-2026-25705

Rancher Extensions have arbitrary file access via path traversal

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.

  *  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.

CWE-35 Path Traversal: '.../...//'

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory.
