CVE-2026-64866: CWE-862: Missing Authorization in QuantumNous new-api
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.
AI Analysis
Technical Summary
QuantumNous new-api, an LLM gateway and AI asset management system, contains a missing authorization check (CWE-862) in the AdminResetPasskey controller function for the DELETE /api/user/:id/reset_passkey endpoint. From versions 0.9.1.3 until 1.0.0-rc.7, the canManageTargetRole authorization check was not enforced, allowing lower-privileged administrators to remove passkeys from accounts with equal or higher privileges, including root. This could lead to unauthorized credential removal and potential privilege disruption. The vulnerability is addressed in version 1.0.0-rc.7.
Potential Impact
An attacker with lower-privileged administrator access can remove passkeys from accounts with the same or higher privileges, including root accounts. This could disrupt account access controls and potentially enable privilege escalation or denial of service on critical accounts. However, exploitation requires existing administrator privileges.
Mitigation Recommendations
Upgrade QuantumNous new-api to version 1.0.0-rc.7 or later where the missing authorization check is implemented. No other mitigation or workaround is specified. Patch status is not explicitly confirmed but the issue is stated as fixed in 1.0.0-rc.7.
