Objective

Find the flag (FLAG{...}) hidden in the application.

The brief for this lab lives in its repository.

Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/xben-091-jwt-tamper && cd xben-091-jwt-tamper && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
