I built some vulnerable LLM apps to show-casing some vulnerabilities.
https://www.shinohack.me/shinollmapp/
You can find the vulnerability for each app, in black tag.
The first app "Alex" has no vulnerability because the only input is date and it is not something that we (hackers) can control. My favorite apps are Emily and Hannah, they allow you to control the price, quantity or perform deadily RCE💀.
I will post the solution for each app later. So please stay tuned.
