FKIE_CVE-2026-10720

Vulnerability from fkie_nvd - Published: 2026-06-19 06:17 - Updated: 2026-06-19 06:17
Severity
5.1 (Medium) - CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:N/VI:L/VA:L/SC:N/SI:H/SA:H
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.
