Summary
Incus: Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge
Details

Incus is a system container and virtual machine manager. Prior to version 7.3.0, when copying an instance across projects, the project restriction check (AllowInstanceCreation) runs BEFORE the source instance's configuration is merged into the request. Dangerous configuration keys (including security.privileged, raw.lxc, raw.apparmor) from the source instance are merged AFTER the check passes, bypassing all project restrictions on the target project. Version 7.3.0 patches the issue.
