Not exactly, the chromium/chrome sandbox isn’t dependent on how and what code you execute the electron/node one is and that is because the latter were designed to execute code across many more privilege levels than what “dedicated” browser needs.
If I download and build chromium (as long as I don’t disable the sandbox altogether) I don’t actually need to think about those issues while I do need to do that with Electron.
Electron has local file access, etc. in fact, it states: “Under no circumstances should you load and execute remote code with Node.js integration enabled.”
So, Stealth should consider forking Electron if better sandboxing is needed.
