An authenticated remote attacker with instance-creation permission in a restricted project can craft a backup archive where backup.yaml carries restricted settings such as security.privileged=true or raw.lxc directives, bypassing all project restriction enforcement and allowing full host compromise.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":9.1,"severity":null}],"references":["https://github.com/canonical/lxd/security/advisories/GHSA-q96j-3fmm-7fv4","https://github.com/canonical/lxd/pull/17921"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-20874","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Apr 9, 2026, 9:18:58 AM","dateUpdated":"Apr 9, 2026, 11:55:20 AM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
