If an admin page is protected by custom route middleware (say EnsureUserIsAdmin), Livewire only applies it on the initial page load. Every later click goes to /livewire/update, which does not re-run that middleware unless you tell it to. So any logged-in user who can grab a component snapshot can call its public methods (delete, toggle, etc.).

Fix:

// AppServiceProvider::boot()
Livewire::addPersistentMiddleware([EnsureUserIsAdmin::class]);

Livewire then re-applies that middleware on update requests for components first rendered on a route that had it. Built-ins like auth are already persistent; your own middleware isn't.

Belt and braces for destructive methods:

public function deleteUser(): void
{
    abort_unless(auth()->user()?->is_admin, 403);
    // ...
}

Testing gotcha: Livewire::test() doesn't run route middleware at all, so a test only catches this if the guard lives inside the method. ->call('deleteUser')->assertForbidden() as a non-admin is a cheap regression test.
