UI Controls Are Not Security Layers: Always Enforce Policies

Hiding buttons in Blade or Vue does not restrict access. Always enforce authorization policies in controller or request layers.

Hiding an edit button using @can or v-if only modifies visual presentation. Attackers can submit HTTP requests directly to backend endpoints. Always enforce authorization logic in backend controllers or form requests.

// Blade UI (Visual convenience only)
@can('update', $post)
    <a href="{{ route('posts.edit', $post) }}">Edit Post</a>
@endcan

// Controller Action (Actual Security Layer)
public function update(UpdatePostRequest $request, Post $post)
{
    $this->authorize('update', $post); // Enforces server-side security
    $post->update($request->validated());
}

• UI directive checks like @can are user-experience features, not security guards
• Always enforce $this->authorize() or Policy checks in backend controllers
• Prevents unauthorized HTTP request payload tampering
