CVE-2026-117564— nest-admin before 1.0.1 Authentication Bypass via Hardcoded JWT Secret

Quick assessment

Affected
buqiyuan nest-admin
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

nest-admin 1.0.1 之前的版本存在认证绕过漏洞。由于生产环境配置文件 中硬编码了 JWT_SECRET，未认证的攻击者可利用该已知密钥伪造管理员令牌。攻击者可以使用该密钥对令牌进行签名，而 JwtStrategy 和 RbacGuard 会信任这些令牌，从而允许攻击者冒充任意用户 ID 或声称拥有管理员角色，进而获取完全的管理访问权限。
