Report: Latest: CVE-2026-34178 - Importing a crafted backup leads to project restriction bypass
CVE ID :CVE-2026-34178 Published : April 9, 2026, 10:16 a.m. | 35 minutes ago Description :In Canonical LXD before 6.8, the backup import path validates project restrictions against backup/index.yaml in the supplied tar archive but creates the instance from backup/container/backup.yaml, a separate file in the same archive that is never checked against project restrictions. 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.
