A Flask page with a text form. The submitted value is rendered back into the HTML response without output encoding.

Objective

Craft input that makes the page run your own JavaScript in the visitor's browser (reflected cross-site scripting).

The brief for this lab lives in its repository.

Submit evidenceSecret

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/skf-xss && cd skf-xss && docker compose up -d

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