Summary
authentik is an open-source identity provider. Prior to 2026.2.7, 2026.5.7, and 2026.8.2, an account with delegated permission to manage a group, group membership, or a user can grant superuser status to an account or assign an existing role to a group without holding the permissions that gate those privileges. Group hierarchy checks do not consistently account for superuser status inherited from ancestor groups, and role assignment to a group lacks the required authorization check. Only deployments that delegate these management capabilities to accounts that are not full administrators are affected. This issue is fixed in versions 2026.2.7, 2026.5.7, and 2026.8.2.
