    Summary: Devise Gem for Ruby Unauthorized Access Using "Remember Me" Cookie

    Details: Devise version before 3.5.4 uses cookies to implement a "Remember me" functionality. However, it generates the same cookie for all devices. If an attacker manages to steal a remember me cookie and the user does not change the password frequently, the cookie can be used to gain access to the application indefinitely.
