DescriptionGitHub Advisory

LaraDashboard is an all-In-one solution to start a Laravel Application. In 2.3.0 and earlier, the password reset flow trusts the Host header, allowing attackers to redirect the administrator’s reset token to an attacker-controlled server. This can be combined with the module installation process to automatically execute the ServiceProvider::boot() method, enabling arbitrary PHP code execution.
