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.\n\n## Affected packages\n\n- `github.com/canonical/microceph/microceph < 0.0.0-20260609072127-5c2760d8fb76`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/canonical/microceph/microceph 0.0.0-20260609072127-5c2760d8fb76`","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
