Description
Incus from 7.3.0 before 7.5.0 contains a project restriction bypass that allows restricted project users to set block.create_options through volume update, copy, and move operations. Attackers can set the option on a custom volume and trigger a copy or move onto a formatting pool to inject arguments into mkfs executed as root.
