Well, Go really isn't inherently safer than Node, it has a similar package ecosystem that could be attacked in the same way.

The only reliable way to be safe when using ANY programming language with packages downloaded from the Internet (which is basically all modern languages) is to run them in a Docker container. That's gonna add a bit of overhead to your system (mostly increased RAM usage), and require downloading even more stuff, but at least whatever damage the thing can do will be contained to its own VM.

Now, what the hell does Playwright have to do with any of that?
