CVE-2026-10720 (GCVE-0-2026-10720)

Vulnerability from cvelistv5 – Published: 2026-06-19 04:57 – Updated: 2026-06-22 15:02

Title

MicroCeph path traversal issue in the remote-import API

Summary

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)
