ZTNET 許可權繞過漏洞：任何使用者可透過 /api/auth/user/invalidateUser 永久停用任意帳號
CVE-2026-62967 - ZTNET privilege bypass: any user can deactivate arbitrary accounts via /api/auth/user/invalidateUser
ZTNET 的 ZeroTier Web UI 在 0.8.0 之前存在許可權繞過漏洞，任何低許可權使用者均可透過 POST /api/auth/user/invalidateUser 永久停用任意帳號，包括管理員。
此漏洞可使低許可權使用者永久停用任意帳號，建議即時升級至 0.8.0 以防止管理層被鎖定。
ZTNET is a ZeroTier web UI for private controllers with multiuser and organization support. Prior to 0.8.0, any authenticated low-privilege user can permanently deactivate another account, including an administrator, through `POST /api/auth/user/invalidateUser`. In `src/pages/api/auth/user/invalidateUser.ts`, `getServerSession` checks only that a session exists and does not compare `session.user.id` with the client-supplied `userId`. Supplying a victim's `userId` and a `deviceId` for which no matching pair exists in `UserDevice` makes the handler set the target account's `isActive` to false. Login is then refused by `src/server/auth.ts` with `account-expired`. An attacker needs only a normal authenticated account and the victim's user ID, which may be obtainable from member lists, UI responses, logs, or other application metadata. This can lock administrators out, disrupt organization management, and deny access to any targeted user. This issue is fixed in version 0.8.0.
