Summary

Incus from 7.3.0 before 7.5.0 contains a project restriction bypass. Restricted project users can set block.create_options through volume update, copy, and move operations. An attacker can set the option on a custom volume and trigger a copy or move onto a formatting pool, which injects arguments into mkfs executed as root (CWE-88).
