Vulnerability Title
Crabbox < v0.12.0 Privilege Escalation via Agent Ticket Endpoints
Source: NVD (National Vulnerability Database)
Vulnerability Description
Crabbox prior to v0.12.0 contains a privilege escalation vulnerability that allows users with shared visibility-only access to obtain Code, WebVNC, and Egress agent tickets by sending POST requests to ticket endpoints. Attackers can exploit insufficient access control checks on the /v1/leases/:id/code/ticket, /v1/leases/:id/webvnc/ticket, and /v1/leases/:id/egress/ticket endpoints to obtain bridge-agent tickets and impersonate trusted lease-side bridges despite having only visibility permissions.

Vulnerability Title
Crabbox 安全漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
Crabbox是openclaw开源的一个远程代码执行与测试环境管理工具。 Crabbox 0.12.0之前版本存在安全漏洞，该漏洞源于访问控制检查不足，可能导致具有共享可见性访问权限的用户通过向/v1/leases/:id/code/ticket、/v1/leases/:id/webvnc/ticket和/v1/leases/:id/egress/ticket端点发送POST请求获取Code、WebVNC和Egress agent票据，从而冒充受信任的租约侧桥接。
