测试代码： https://github.com/r4j0x00/exploits/tree/master/chrome-0day

该漏洞已验证，目前 Google 只针对该漏洞发布了 beta 测试版 Chrome （ 90.0.4430.70 ）修复，Chrome 正式版（ 89.0.4389.114 ）仍存在漏洞，360CERT 建议广大用户关注官方 Chrome 正式版更新，及时修补漏洞。与此同时，请做好资产自查以及预防工作，以免遭受黑客攻击。

不过这个漏洞并不能单独生效，需要配合类似沙箱逃逸这样的漏洞使用，想体验的可以让 Chrome 运行在 –no-sandbox 情况下，会发现计算器弹出来。

the good thing is that Agarwal’s zero-day cannot currently escape the browser’s sandbox. For Agarwal’s zero-day RCE exploit to work, it would need to be chained with another vulnerability that can allow the exploit to escape the Chromium sandbox.
