How to fix?

Upgrade laravel/framework to version 8.83.24 or higher.

Overview

laravel/framework is a PHP framework for web artisans.

Affected versions of this package are vulnerable to Authentication Bypass via timeless timing attacks with HTTP/2 multiplexing. This is caused by the early return inside the hasValidCredentials method in the Illuminate\Auth\SessionGuard class when a user is found to not exist.

Impact: By exploiting this vulnerability an attacker can harvest existing emails (user enumeration).
