CVE-2026-62867
CriticalCVSS 9.9Summary
Incus prior to version 7.3.0 has a vulnerability where improper validation of user-provided `block.create_options` in storage volume configuration leads to argument injection in the constructed filesystem creation command line. This allows a project-scoped user to inject arbitrary arguments into the binary executed as root.
Risk Assessment
A project-scoped user can inject arbitrary arguments into a root process, potentially leading to privilege escalation and full host control.
Recommendation
Update Incus to version 7.3.0 or later, which includes a fix for this issue.
