CVE-2026-64859
Critical
Description
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.
