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.","affected":[{"package":{"name":"github.com/canonical/microceph/microceph","ecosystem":"Go","purl":"pkg:golang/github.com/canonical/microceph/microceph"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20260609072127-5c2760d8fb76"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-xg3j-c7q4-f9ph/GHSA-xg3j-c7q4-f9ph.json"}}],"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-10720"},{"type":"WEB","url":"https://github.com/canonical/microceph/pull/758"},{"type":"WEB","url":"https://github.com/canonical/microceph/commit/5c2760d8fb765d670e2673d3a537b67eae4b67c6"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-xg3j-c7q4-f9ph"},{"type":"PACKAGE","url":"https://github.com/canonical/microceph"}],"database_specific":{"cwe_ids":["CWE-23"],"github_reviewed":true,"github_reviewed_at":"2026-06-19T22:10:23Z","nvd_published_at":"2026-06-19T06:17:00Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"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"}]}
