Laravel 5.4.22 is now released and available. This release fixes a security vulnerability related to the password reset system and everyone should upgrade.

Laravel 5.4.22 patches a security vulnerability in the Laravel 5.4 release series that allows phishing attempts on users of the application. Using the password reset system, malicious users can attempt to trick your users into entering their login credentials into a separate application that they control. Since the password reset notification uses the host of the incoming request to build the password reset URL, the host of the password reset URL may be spoofed. If users do not notice that they are not on their intended application’s domain, they may accidentally enter their login credentials into a malicious application.

The release notes also mention the fix for those running Laravel 5.1 and you need to ensure the password reset link contains the full URL to your site. For example:

{{ url('http://example.com/password/reset/'.$token) }}
