Reset-Token Takeover

The password-reset confirmation trusts a token and a user reference carried in the request — and the token is not unguessable. Complete a reset for an account that is not yours.

Complete password reset

You asked to reset your password. The link we generated for you is below. Confirm it to set a new password. In this sandbox no password actually changes — completing a reset for an account that is not yours reveals the flag.

The user and token are submitted as pinned fields — change them with an intercepting proxy.

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