Explore the application as a real target: map the exposed functionality, inspect requests and responses, build a working exploit, and recover the rotating flag. If you get stuck, the verified official solution is available below as an optional spoiler.
Rules of engagement
Stay inside the generated lab URL. Use only the synthetic accounts and data in this instance. The main SecOne4all site and external systems are out of scope.
Challenge brief
What counts as a valid solve
Move a request directly from draft to paid without required review states.
POST /request-state.
leave the workflow in the prohibited synthetic state described by the business rule; the successful workflow returns the current rotating flag.
Work only inside your generated lab URL and submit the flag within 35 minutes.

Objective
Move a request directly from draft to paid without required review states.
Steps
- Start the isolated lab and read the normal business rule returned by the vulnerable workflow.
- Perform the legitimate first step so the synthetic record, balance, token, or state exists.
- Break the workflow invariant: POST
/request-statewithstatus=paid, skipping the advertised review transition. - Confirm the violated rule returns the rotating instance flag.
- Submit that flag before the instance expires or is stopped.
Expected proof
A successful response for workflow-state-skip returns the instance-specific rotating flag. The flag is valid only for the current player and running instance.
Safety boundary
Use only the generated lab URL. No request to the main site, another user, or an external service is part of this solution.
