Hi @revelt ! I'm sorry, i just recently noticed you tried to fix detect-non-literal-fs-filename with this PR.
I also noticed the rule only works in very special cases and does not cover a lot of them.

So my decision was to rewrite the rule. It's currently in a WIP state on my fork: https://github.com/BuZZ-T/eslint-plugin-security/tree/feature/extend-detect-non-literal-fs-filename

I also want to check if the import is really from "fs" / "node:fs" / "fs/promises" / etc...

I'd really appreciate comments once my PR is ready. I'll inform you, if you want
