Vulnerability Title
New API: Admin can reset passkeys for same-level or higher-privileged users
Source: CVE Program / CVE List V5
Vulnerability Description
New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. From 0.9.1.3 until 1.0.0-rc.7, AdminResetPasskey in controller/passkey.go lacks the canManageTargetRole authorization check for DELETE /api/user/:id/reset_passkey, allowing a lower-privileged administrator to remove a passkey from a same-level or higher-privileged account, including a root account. This issue is fixed in version 1.0.0-rc.7.
