CVE-2026-62941: Lxc Incus

Critical severity, CVSS 9.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Lxc Incus: before 7.3.0 (fixed in 7.3.0)
