Upgrade github.com/canonical/lxd/lxd to version 6.8 or higher.
Overview
Affected versions of this package are vulnerable to Improper Validation of Consistency within Input through the internalImportFromBackup process in lxd/api_internal.go. An attacker can create a backup archive with a benign backup/index.yaml and a malicious backup/container/backup.yaml, then import it into a restricted project to get an instance created with security.privileged=true, raw.lxc overrides, or restricted device attachments. The imported instance is built from the unchecked backup configuration, letting a tenant with instance-creation rights in a restricted project start a container that can mount host resources and gain full LXD administrative control.
