Quick assessment

Affected
openclaw crabbox
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.

Crabbox是openclaw开源的一个远程代码执行与测试环境管理工具。 Crabbox 0.9.0之前版本存在安全漏洞，该漏洞源于协调器用户令牌验证路径中的认证绕过，verifyUserToken函数未能拒绝包含admin声明的有效载荷，可能导致攻击者提升权限。具有共享非管理员令牌访问权限的攻击者可构造包含admin: true的用户令牌有效载荷，使用HMAC-SHA256签名，并将其呈现给仅管理员协调器路由，从而获得完全协调器管理员访问权限，包括租约可见性、池状态管理和强制释放操作。

Vulnerability Title
Crabbox < 0.9.0 Authentication Bypass via Admin Claim Injection
Source: CVE Program / CVE List V5
Vulnerability Description
Crabbox before 0.9.0 contains an authentication bypass vulnerability in the coordinator user-token verification path where the verifyUserToken() function fails to reject payloads containing an admin claim, allowing attackers to escalate privileges. An attacker with access to the shared non-admin token can craft a user-token payload with admin: true, sign it using HMAC-SHA256, and present it to admin-only coordinator routes to gain full coordinator admin access including lease visibility, pool state management, and forced release operations.
