CVE-2026-10720
MediumCVSS 5.1Summary
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 or join token can manipulate files in an imported remote cluster.
Risk Assessment
This could lead to daemon disruption and pollution of the cluster state, jeopardizing system integrity.
Recommendation
It is recommended to update to the latest version of MicroCeph and restrict access to trusted certificates and join tokens.
Original NVD description (English source)
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.
