Vulnerability from github – Published: 2026-06-19 06:31 – Updated: 2026-06-19 22:10

Summary

Canonical MicroCeph: path traversal issue in the remote-import AP

Details

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.

Severity

5.1 (Medium)
