Flakes introduced a concept of trusted list which are list of Flakes which are allowed to mess with your nixConfig, they are allowed to set options such as sandbox = false; or new substituters or their keys.

Lix documented a couple of times that this capability is a gigantic risk and you should never run with --accept-flake-config blindly, if you are not willing to be pwned, that is.

That being said, if you allow permanently a well chosen set of Flakes, you should be able to review this list. It's a simple JSON file that lives into your ~/.local/share/nix/trusted-settings.json usually but Lix offers no tool to manipulate it: read it, clear it, etc.

This shall be fixed.
