Mautic allows users enumeration due to weak password login
Summary
When logging in with the correct username and incorrect weak password, the user receives the notification, that their password is too weak.
However when an incorrect username is provided along side with weak password, the application responds with ’Invalid credentials’ notification.
This difference could be used to perform username enumeration.
