    CVE-2026-62867

    Incus is a system container and virtual machine manager. Prior to version 7.3.0, 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. Version 7.3.0 patches the issue.
