Misc
1. Easy Jail
One popular type of challenge in many CTFs is the "Jail Challenge", which has players try to escape a code sandbox with some sort of restriction applied. When I checked the source code, I noticed that there were no filters or restrictions on user input.
This means we can easily send our payload like this.
