CVE-2026-94609— authentik: Privilege Escalation to Superuser via Group Hierarchy

Quick assessment

Affected
goauthentik authentik
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

authentik 是一个开源的身份提供商。在 2026.2.7、2026.5.7 和 2026.8.2 版本之前，一个拥有委托权限用于管理组、组成员关系或用户的账户，可以在未持有相应权限的情况下，将超级用户权限授予某个账户或将已有角色分配给某个组。组层级检查并未始终考虑从祖先组继承而来的超级用户状态，且向组分配角色时缺少必需的授权检查。此问题仅影响那些将此类管理能力委托给非完整管理员账户的部署环境。该问题已在 2026.2.7、2026.5.7 和 2026.8.2 版本中得到修复。

Vulnerability Title
authentik: Privilege Escalation to Superuser via Group Hierarchy
Source: CVE Program / CVE List V5
Vulnerability Description
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.
