CVE-2026-62313

Incus is a system container and virtual machine manager.

Published Aug 21, 2026 · updated Oct 15, 2026

Incus is a system container and virtual machine manager. Prior to version 7.3.0, project-level enforcement of can be trivially bypassed, allowing a user to create a non-isolated (shared host idmap) container in a project that is configured to forbid them. The restriction only rejects an explicitly set (or empty) and fails to enforce anything when the key is omitted entirely. Because an unset defaults to (non-isolation), a user simply leaves the key out and obtains exactly the container state the restriction is meant to forbid. This defeats the tenant-isolation guarantee the restriction exists to provide. Containers in the project share the host uid/gid map instead of receiving unique, non-overlapping ranges, weakening the isolation boundary between co-tenant containers and the host. Version 7.3.0 patches the issue.
