What This Checks ​

This analyzer validates the security configuration of Laravel Nova to ensure the admin panel is not publicly accessible and has proper authorization controls at multiple levels.

Checks Performed:

Service Provider Validation ​

  • NovaServiceProvider existence - Verifies the file exists; if missing, Nova has no authorization gate
  • Authorization gate - Checks for Gate::define('viewNova', ...) (Nova 4/5) or Nova::auth() (Nova 3 legacy)
  • Empty gate() method - Flags a gate() method with no Gate::define('viewNova') call
  • Hardcoded return true - Flags callbacks that unconditionally return true
  • Arrow function shorthand - Flags fn($user) => true gate definitions
  • Auth-only gate - Flags callbacks that only verify authentication without checking roles or permissions
  • Permissive fallback - Flags ?? true or ?: true in the gate expression
  • Environment bypass - Flags environment conditions (staging, testing, dev) or config('app.debug') used as the sole authorization check

Configuration Validation ​

  • Stripped middleware - Flags when middleware contains only 'web', meaning Nova's own middleware have been removed
  • Missing Authenticate middleware - Flags when api_middleware does not include Authenticate::class
  • Missing Authorize middleware - Flags when api_middleware does not include Authorize::class
  • Predictable path - Warns when path is set to /nova or /admin

Resource Authorization ​

  • Disabled authorization - Flags Nova resource classes where authorizable() returns false, disabling all policy checks

Tool Authorization ​

  • Missing canSee() - Flags tools registered without a ->canSee() authorization callback
  • Permissive canSee() - Flags tools where canSee() unconditionally returns true

Why It Matters ​

An unsecured Nova admin panel provides complete administrative access to your application, exposing:

  • Full database access - CRUD operations on all application resources and sensitive data
  • User management - Ability to create, modify, and delete user accounts including administrators
  • Application configuration - Settings, feature flags, and system configuration changes
  • File management - Upload, download, and delete files through Nova file fields
  • Custom actions - Execution of bulk operations, data exports, and administrative actions

A publicly accessible Nova panel is equivalent to giving an attacker full database admin access with a user-friendly interface.

How to Fix ​

Quick Fix (5 minutes) ​

Define the viewNova gate in your NovaServiceProvider:

Before (❌):

php
// app/Providers/NovaServiceProvider.php
class NovaServiceProvider extends NovaApplicationServiceProvider
{
    protected function gate(): void
    {
        // No gate defined — any authenticated user can access Nova
    }
}

After (✅):

php
// app/Providers/NovaServiceProvider.php
use Illuminate\Support\Facades\Gate;

class NovaServiceProvider extends NovaApplicationServiceProvider
{
    protected function gate(): void
    {
        Gate::define('viewNova', function ($user) {
            return $user->hasRole('admin');
        });
    }
}

Nova 3 Legacy Pattern

If you are on Nova 3, use Nova::auth() inside boot() instead of Gate::define() inside gate(). Nova 4 and 5 use the Gate::define('viewNova', ...) approach shown above.

Proper Fix (15 minutes) ​

Step 1: Define a strong authorization gate

php
// app/Providers/NovaServiceProvider.php
use Illuminate\Support\Facades\Gate;

class NovaServiceProvider extends NovaApplicationServiceProvider
{
    protected function gate(): void
    {
        Gate::define('viewNova', function ($user) {
            return $user->hasRole('admin') || $user->hasRole('super-admin');
        });
    }
}

Step 2: Verify config/nova.php retains Nova's default middleware

php
// config/nova.php
return [
    'path' => env('NOVA_PATH', 'manage'),   // avoid predictable /nova or /admin

    // Web middleware: Nova UI delivery — do not add 'auth' here
    'middleware' => [
        'web',
        \Laravel\Nova\Http\Middleware\HandleInertiaRequests::class,
        \Laravel\Nova\Http\Middleware\DispatchServingNovaEvent::class,
        \Laravel\Nova\Http\Middleware\BootTools::class,
    ],

    // API middleware: authentication and gate enforcement
    'api_middleware' => [
        'nova',
        \Laravel\Nova\Http\Middleware\Authenticate::class,
        \Laravel\Nova\Http\Middleware\Authorize::class,
    ],
];

Step 3: Do not disable resource authorization

php
// app/Nova/User.php

// WRONG (❌) — disables all policy checks for this resource
public static function authorizable(): bool
{
    return false;
}

// CORRECT (✅) — remove the override entirely, or register a policy
// php artisan nova:policy User

Step 4: Authorize custom tools

php
// app/Providers/NovaServiceProvider.php
public function tools(): array
{
    return [
        (new \App\Nova\Tools\AuditLog)->canSee(
            fn ($request) => $request->user()->hasRole('super-admin')
        ),
    ];
}
