How this works?
Mod checking version from json file from link, then check version from .zip, and if version from json file greater that version in .zip, mod replace resource pack to new pack from link located in json.
Can author download exploit in your pc with this mod?
Literally no. But she/he can put zip bomb into pack... And this is doesn't under my control, sorry. So, download packs only from places you trust :)
