CVE-2026-55621
Incus has a project restriction bypass for custom volume copy across projects
Impact
Incus is a system container and virtual machine manager. Prior to version 7.2.0, missing authorization checks exist for custom volume copying where an attacker knowing the name of a project that they don't have access to and the name of a custom volume in that project can copy the custom volume to a new project. This issue could allow an attacker to access secrets in custom volumes they are not authorized to access. Version 7.2.0 patches the issue.
