Just remember that just because you're using .ini/.json/.toml files doesn't mean there isn't any way of executing code from changing their values, it's up to whatever is using the files if there is any way of executing code via them.
One example is package.json. It's a JSON file, yeah, and normally doesn't contain any code. But one of the fields is `scripts` which can contain a object with a key like `preinstall` (and more) that runs those as shell commands at different lifecycle of using `npm`.
So just because you're using those languages/syntaxes, doesn't mean there isn't any way of executing code via them.
