CVE-2026-64859 PUBLISHED

New API: User List API Leaks Root User Access Token Leading to Privilege Escalation

Assigner: GitHub_M
Reserved: 20.07.2026 Published: 17.08.2026 Updated: 17.08.2026

New API is a large language mode (LLM) gateway and artificial intelligence (AI) asset management system. Prior to 1.0.0-rc.7, the admin user list and user lookup APIs, including GET /api/user/, return User.AccessToken as access_token because User model objects are serialized after queries use Omit("password"), allowing an authenticated administrator to obtain the root user's bearer token and access root-only system configuration APIs. This issue is fixed in version 1.0.0-rc.7.
