CVE-2026-62940
CriticalCVSS 9.9Summary
Incus prior to version 7.3.0 has a vulnerability where 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.
Risk Assessment
A user from a restricted project can gain privileged access to a container and escape to the host, leading to full system compromise.
Recommendation
Update Incus to version 7.3.0 or later, which includes a fix for this issue.
