An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass project-level container isolation restrictions. When a project is configured with restrictions on container privileges (such as enforcing restricted.containers.privilege=isolated), LXD fails to enforce the requirement if an instance configuration omits the security.idmap.isolated key. An attacker can exploit this flaw by creating or updating an instance without explicitly setting security.idmap.isolated, bypassing the target project's security constraints.

Nil-pointer dereference in CreateCustomVolumeFromBackup in LXD up to version 6.8 and 5.21 on Linux allows an authenticated user with cancreatestoragevolumes permissions to cause a denial of service via a specially crafted custom-volume backup tarball that omits the expiresat snapshot field.

Path traversal in Canonical LXD LXD-UI versions before 6.5 and 5.21.4 on all platforms allows remote authenticated attackers to access or modify unintended resources via crafted resource names embedded in URL paths.
