Reported on

Oct 9th 2021


There is no rate limit sent unlimited email victim or any email address.

Proof of Concept:

There is no rate limit return-password , attacker to send unlimited email to victim or any email address.


Attacker can sent unlimited email to any mail address .


Add 'throttle' => 60, to auth.php config or $this->middleware('throttle:3,1') to the forgot password controller construct.
