Description

Incus is a system container and virtual machine manager. Prior to version 7.3.0, when migrating an instance to another cluster member, user-supplied configuration overrides (including security-critical keys like `security.privileged` and `raw.lxc`) are applied without any project restriction enforcement, allowing a restricted project user to escalate to a privileged container and escape to the host. Version 7.3.0 patches the issue.
