A POST to /login carrying submit_reset and a username needs no authentication: it stores a fresh reset code against that account and mails the account holder a link to a host of the sender\u0027s choosing. The welcome mail takes the same path when the application calls create_user with email_welcome set.\n\nThrough 0.711 the handlers read `request-\u003euri_base` and `request-\u003ebase` directly; Versions 0.712 and later provide an uri_base configuration key that defaults to the untrusted `request-\u003euri_base` when unset.\n\nThe default configuration with reset_password_handler enabled and the default message text, a recipient who follows the link hands a working reset code to the sender\u0027s host, which is enough to take over the account."
