I found a remote code execution bug in VSCode that can be triggered from untrusted workspaces. Microsoft fixed it but marked it as moderate severity and ineligible under their bug bounty program.

Is there a way to dynamically interpret a string as javascript within a C# winforms program?
I've used ClearScript before to use JavaScript as a DSL in a tool. No issues at all. https://github.com/microsoft/ClearScript

Lua or JavaScript as an extension language?
I've had good luck with Microsoft's Clearscript - https://github.com/microsoft/ClearScript)

Scripting languages that use host language's libraries?
The ClearScript library https://github.com/microsoft/ClearScript enables V8, JScript and VBScript to be used as extension languages for .NET languages. Our company uses it extensively and has done so with great success for years. Anything done in C# can be exposed to the scripting language and to some extent back the other way as well.

Scripting inside Rimworld with Unity: Impossible? With java it is a 3 liner.
There are quite a lot of ways to run scripting languages in C#. I've no idea what JSR223 is but .NET has DLR for example. There are also multiple libraries: IronPython, NLua, Jint and Jurassic for Javascript. There's also older version of CS-Script working with .NET Framework.

Is there any way to use Javascript to code in Unity anymore?
You can. Embeding lua is a trivial task, and I'm reasonably sure there even are plug-and-play solutions for that, and for JS there's JINT.

Running custom code from users
I personally use Jint (a multi-platform Javascript interpreter) since Roslyn is not available on mobile. It basically has the same kind of functionality as Roslyn, but it's JS. JS is well-known and accessible to everybody, but Roslyn might be faster since there's no double indirection when interpreting the script. It also depends on what language your users are comfortable with or could learn easily.

Classic BBS (code in comments)
Ah yeah, I looked into it more and decompiled the game to find that it appears they're using Jint to interpret the Javascript, and from testing with someone's REPL BBS server I can find that it's a pretty well isolated environment. Only ways around it I can think of are by exploiting some vulnerability in the sandbox to do external requests, modding the game itself to update the api, or running a parallel server to do some janky communication through the save state data.

.NET-compatible scripting languages for users to write their own scripts to query/manipulate objects/properties in the app
We used https://github.com/sebastienros/jint for scripting, it's ES5 JS implementation.

The experience of creating my own JavaScript runtime - #2
Jint is a JS interpreter with an integrated engine built in C#, like V8, he is responsible for all the base code execution as well as EcmaScript implementations such as default constructors, syntax, Promises... I studied its features in depth to start and it was a bit hard (in the beginning).

The experience of creating my own JavaScript runtime - #1
MelonRuntime is based on Jint, a JavaScript interpreter created by Sébastien Ros, software developer in the ASP.NET team at Microsoft. Melon works from bindings and functionalities injected into this interpreter together with external typing (provided by another package that comes with the default project generated by the command npx melon new) and built-in tools.
