Redirect Level 5 / 6 Hard

Fragment Token Theft

A redirect carries a token in the URL fragment. Steal it via the redirect.

Uncrypt SSO — sign-in complete

After login, the SSO service redirects to your return URL and appends the freshly minted session token in the fragment (#access_token=…). Steal that token by choosing where the flow returns to.

This is an isolated, intentionally-vulnerable sandbox. Data here is fake and scoped to you. The rest of Uncrypt Playground is not part of the target.
