## Overview

Canonical MicroCeph versions from the squid and tentacle track are vulnerable to a path traversal issue in the remote-import API. Holders of a trusted cluster mTLS certificate (such as enrolled cluster members) or join token can manipulate files in an imported remote cluster within the /var/snap/microceph confinement. This would allow daemon disruption and pollution of the cluster state.

## Affected packages

- `github.com/canonical/microceph/microceph < 0.0.0-20260609072127-5c2760d8fb76`

## Remediation

Upgrade to a patched release:

- `github.com/canonical/microceph/microceph 0.0.0-20260609072127-5c2760d8fb76`
