Quick assessment

Affected
Th0rgal sandboxed.sh
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.

sandboxed.sh 1.3.0 及更早版本存在一个容器逃逸漏洞，该漏洞允许容器工作区中的代码访问宿主机文件系统，因为 nsenter 在附加时未使用 --root 参数。在容器工作区中运行的代理代码可以解析宿主机上的绝对路径，从而读取和修改宿主机文件，绕过了文档中描述的隔离机制。
