The Feather Login Page plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions starting from 1.0.7 up to, and including, 1.1.1. This is due to missing nonce validation in the 'createTempAccountLink' function. This makes it possible for unauthenticated attackers to create a new user with administrator role via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. An attacker can leverage CVE-2023-2545 to get the login link or request a password reset to the new user's email address.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
