Overview

Affected versions of this package are vulnerable to Authentication Bypass when a password's salt is unknown. If the secret key base variable is somehow leaked, an attacker can become any user by misusing the masquerade back functionality of this Devise extension, something that is not possible in plain Devise since the attacker must know the victim's password salt to form a valid session cookie to encrypt and sign using secret key base.
