Objective

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

The brief for this lab lives in its repository.

Exploit cross-site scriptingHTTP

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-087-cross-30 && cd xben-087-cross-30 && docker compose up -d

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