iOS 18, Nugget, and Jailbreaking

TLDR: I’m a scrub at iOS security and wondering how far the sparserestore exploit can go

Hello everyone. Just today, I noticed Nugget received an update, releasing version 2.0.1 which indicated the developer made changes to how the exploit handles domain. I am on iOS 18.1 on my iPhone 15 PM, and as of writing this post, Nugget Mobile does seem to work, as seen in the screenshots by the minor tweaks I’ve done to my iPhone.

So, I am a pretty simple man. I don’t know how to find exploits, develop code, or dump the filesystem of an iOS device. I am, however, like many here, an enthusiast of being able to do whatever I please with the device I own, damn the risks. This had me thinking a bit. With how fast Nugget was released, I was thinking a jailbreak may be on the horizon. From what I understand, Nugget uses the sparserestore exploit to target particular filesystem structures (domains) and make modifications to one’s MobileGestalt plist file, which is located in the Private/Var directory. If this is possible, what stops this from becoming a full blown exploit to modify any system file?
