Are there any security issues in sending json data, b/w .NET app and React app running in Cef browser, through Cef events?

[Ayyappu]

I have a .NET (WinForms) app. A React app can be launched from inside the WinForms app (this React app is loaded in Cef browser). I am able to send data between the 2 apps (WinForms and React inside Cef) using ExecuteJavaScriptAsync method. I noticed that I am able to send json data of any size i.e., there are no size limitations. Is sending such a big json data via Cef events safe? Can the confidential json data be hacked by anyone?

In future please ask your question in a single place, either here or GitHub, not both. Thanks.
