Objective

Loopline. A Mongo query that takes your JSON at face value — inject the operators it never expected.

How to play

Open the target in your browser, find the flaw, and exploit it. On success the page reveals the login for the next level — that password is this level's flag. Submit it on the track page (or /submit) to bank the points.
