Kirby CMS vulnerable to user enumeration in the code-based login and password reset forms

• ECOSYSTEM: introduced 3.5.0; fixed 3.5.8.2

### TL;DR This vulnerability only affects you if you are using the `code` or `password-reset` auth method with the `auth.methods` option. It can only be successfully exploited under server configuration conditions outside of the attacker's control. ---- ### Introduction User enumeration is a type of vulnerability that allows attackers to confirm which users are registered in a Kirby installation. This information can be abused for social engineering attacks against users of the site or to find out the organizational structure of the company. User enumeration attacks are performed by entering an existing and a non-existing user into the email address field of the login form. If the system returns a different response or behaves differently depending on whether the user exists, the attacker can enter unknown email addresses and use the different behavior as a clue for the (non-)existing user. ### Impact Under normal circumstances, entering an invalid email address results in a "fake" login code form that looks exactly like the one of an existing user (unless debugging is enabled). However, the code that handles the creation of a code challenge (for code-based login or password
