OpenHands 软件代理 SDK 在 1.52.0 之前的版本中存在一个无需认证的远程代码执行漏洞。该漏洞源于 DockerWorkspace 和 Apptainer 工作区启动器将沙箱代理服务器绑定到所有网络接口（0.0.0.0），同时将 session_api_keys 列表设置为空，导致默认情况下认证功能被禁用。能够访问已发布容器端口的攻击者可以发送未经认证的 HTTP 和 WebSocket 请求，从而在沙箱中以 root 用户身份执行任意 shell 命令、访问挂载的工作区，并读取秘密存储中的明文密钥

Vulnerability Title
OpenHands Software Agent SDK < 1.52.0 Unauthenticated Sandbox Agent Server RCE
Source: CVE Program / CVE List V5
Vulnerability Description
OpenHands Software Agent SDK before 1.52.0 contains an unauthenticated remote code execution vulnerability where the DockerWorkspace and Apptainer workspace launchers bind the sandbox agent server to all network interfaces (0.0.0.0) with an empty session_api_keys list, disabling authentication by default. Attackers who can reach the published container port can send unauthenticated HTTP and WebSocket requests to execute arbitrary shell commands as root in the sandbox, access the mounted workspace, and read plaintext secrets from the secrets store.
