{"id":"CVE-2026-6369","state":"PUBLISHED","title":"Exposed Session Token in canonical-livepatch client snap","description":"An improper access control vulnerability in the canonical-livepatch snap client prior to version 10.15.0 allows a local unprivileged user to obtain a sensitive, root-level authentication token by sending an unauthenticated request to the livepatchd.sock Unix domain socket. This vulnerability is exploitable on systems where an administrator has already enabled the Livepatch client with a valid Ubuntu Pro subscription. This token allows an attacker to access Livepatch services using the victim's credentials, as well as potentially cause issues to the Livepatch server.","publishedAt":"2026-04-20T13:38:13.691Z","updatedAt":"2026-04-20T14:06:18.537Z","severity":{"score":5.7,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:L/SA:L","source":"canonical"},"assigner":"canonical","products":["Canonical canonical-livepatch"],"affected":[{"vendor":"Canonical","product":"canonical-livepatch","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"10.15.0","versionType":"semver"}]}],"references":["https://discourse.ubuntu.com/t/security-notice-canonical-livepatch-client-snap-vulnerability/80662"],"weaknesses":["CWE-306","CWE-732"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6369.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6369","state":"PUBLISHED","datePublished":"2026-04-20T13:38:13.691Z","dateUpdated":"2026-04-20T14:06:18.537Z","assignerShortName":"canonical","assignerOrgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","dateReserved":"2026-04-15T15:52:27.875Z"},"containers":{"cna":{"title":"Exposed Session Token in canonical-livepatch client snap","descriptions":[{"lang":"en","value":"An improper access control vulnerability in the canonical-livepatch snap client prior to version 10.15.0 allows a local unprivileged user to obtain a sensitive, root-level authentication token by sending an unauthenticated request to the livepatchd.sock Unix domain socket. This vulnerability is exploitable on systems where an administrator has already enabled the Livepatch client with a valid Ubuntu Pro subscription.
