Specifically, the Juju controller's database endpoint does not validate client certificates when a new node attempts to join the cluster. An unauthenticated attacker with network reachability to the Juju controller's Dqlite port can exploit this flaw to join the database cluster. Once joined, the attacker gains full read and write access to the underlying database, allowing for total data compromise.","state":0,"publishedAt":"2026-04-01T09:16:17.717+00:00","modifiedAt":"2026-10-26T21:10:00.17+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security@ubuntu.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10,"severity":"CRITICAL"}],"references":["https://github.com/juju/juju/security/advisories/GHSA-gvrj-cjch-728p"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-4370","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-295","CWE-306"],"productCriteria":["cpe:2.3:a:canonical:juju:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-04-01T09:16:17.717","lastModified":"2026-10-26T21:10:00.170"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
