Detailed vulnerability description
The vulnerability allows a remote attacker to take over a user account.
The vulnerability exists due to improper neutralization of special elements in output used by a downstream component in the password reset functionality in src/Controller/Admin/UserController.php when generating password reset links from the Host header of a request. A remote attacker can send a password reset request with a crafted Host header to take over a user account.
User interaction is required to click the crafted password reset link, and exploitation requires the application to accept arbitrary Host headers.
