Summary
Sylius affected by IDOR in Cart and Checkout LiveComponents
Details

Impact

An authenticated Insecure Direct Object Reference (IDOR) vulnerability exists in multiple shop LiveComponents due to unvalidated resource IDs accepted via #[LiveArg] parameters. Unlike props, which are protected by LiveComponent's @checksum, args are fully user-controlled - any action that accepts a resource ID via #[LiveArg] and loads it with ->find() without ownership validation is vulnerable.

Checkout address FormComponent (addressFieldUpdated action): Accepts an addressId via #[LiveArg] and loads it without verifying ownership, exposing another user's first name, last name, company, phone number, street, city, postcode, and country.

Cart WidgetComponent (refreshCart action): Accepts a cartId via #[LiveArg] and loads any order directly from the repository, exposing order total and item count.

Cart SummaryComponent (refreshCart action): Accepts a cartId via #[LiveArg] and loads any order directly from the repository, exposing subtotal, discount, shipping cost, taxes (excluded and included), and order total.

Since sylius_order contains both active carts (state=cart) and completed orders (state=new/fulfilled) in the same ID space, the cart IDOR exposes data from all orders, not just active carts.

Patches

The issue is fixed in versions: 2.0.16, 2.1.12, 2.2.3 and above.

Workarounds

Override vulnerable LiveComponent classes at the project level to add authorization checks to #[LiveArg] parameters.

Step 1. Exclude component overrides from default autowiring

In config/services.yaml, add Twig/Component to the exclude list to prevent duplicate service registration:

App\:
    resource: '../src/*'
    exclude: '../src/{Entity,Kernel.php,Twig/Components}'

Step 2. Override checkout address FormComponent

Create src/Twig/Components/Checkout/Address/FormComponent.php:

<?php

declare(strict_types=1);

namespace App\Twig\Components\Checkout\Address;

use Sylius\Bundle\ShopBundle\Twig\Component\Checkout\Address\AddressBookComponent;
use Sylius\Bundle\UiBundle\Twig\Component\ResourceFormComponentTrait;
use Sylius\Bundle\UiBundle\Twig\Component\TemplatePropTrait;
use Sylius\Component\Core\Model\OrderInterface;
use Sylius\Component\Core\Model\ShopUserInterface;
use Sylius\Component\Core\Repository\AddressRepositoryInterface;
use Sylius\Component\Core\Repository\OrderRepositoryInterface;
use Sylius\Component\Customer\Context\CustomerContextInterface;
use Sylius\Component\User\Repository\UserRepositoryInterface;
use Symfony\Component\Form\FormFactoryInterface;
use Symfony\Component\Form\FormInterface;
use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
use Symfony\UX\LiveComponent\Attribute\LiveArg;
use Symfony\UX\LiveComponent\Attribute\LiveListener;
use Symfony\UX\LiveComponent\Attribute\LiveProp;
use Symfony\UX\LiveComponent\Attribute\PreReRender;

#[AsLiveComponent]
class FormComponent
{
    /** @use ResourceFormComponentTrait<OrderInterface> */
    use ResourceFormComponentTrait;
    use TemplatePropTrait;

    #[LiveProp]
    public bool $emailExists = false;

    /**
     * @param OrderRepositoryInterface<OrderInterface> $repository
     * @param UserRepositoryInterface<ShopUserInterface> $shopUserRepository
     */
    public function __construct(
        OrderRepositoryInterface $repository,
        FormFactoryInterface $formFactory,
        string $resourceClass,
        string $formClass,
        protected readonly CustomerContextInterface $customerContext,
        protected readonly UserRepositoryInterface $shopUserRepository,
        protected readonly AddressRepositoryInterface $addressRepository,
    ) {
        $this->initialize($repository, $formFactory, $resourceClass, $formClass);
    }

    #[PreReRender(priority: -100)]
    public function checkEmailExist(): void
    {
        $email = $this->formValues['customer']['email'] ?? null;
        if (null !== $email) {
            $this->emailExists = $this->shopUserRepository->findOneByEmail($email) !== null;
        }
    }

    #[LiveListener(AddressBookComponent::SYLIUS_SHOP_ADDRESS_UPDATED)]
    public function addressFieldUpdated(#[LiveArg] mixed $addressId, #[LiveArg] string $field): void
    {
        $customer = $this->customerContext->getCustomer();
        if (null === $customer) {
            return;
        }

        // Fix: findOneByCustomer instead of find — validates ownership
        $address = $this->addressRepository->findOneByCustomer((string) $addressId, $customer);
        if (null === $address) {
            return;
        }

        $newAddress = [];
        $newAddress['firstName'] = $address->getFirstName();
        $newAddress['lastName'] = $address->getLastName();
        $newAddress['phoneNumber'] = $address->getPhoneNumber();
        $newAddress['company'] = $address->getCompany();
        $newAddress['countryCode'] = $address->getCountryCode();
        if ($address->getProvinceCode() !== null) {
            $newAddress['provinceCode'] = $address->getProvinceCode();
        }
        if ($address->getProvinceName() !== null) {
            $newAddress['provinceName'] = $address->getProvinceName();
        }
        $newAddress['street'] = $address->getStreet();
        $newAddress['city'] = $address->getCity();
        $newAddress['postcode'] = $address->getPostcode();

        $this->formValues[$field] = $newAddress;
    }

    protected function instantiateForm(): FormInterface
    {
        return $this->formFactory->create(
            $this->formClass,
            $this->resource,
            ['customer' => $this->customerContext->getCustomer()],
        );
    }
}

Step 3. Override cart WidgetComponent

Create src/Twig/Components/Cart/WidgetComponent.php:

<?php

declare(strict_types=1);

namespace App\Twig\Components\Cart;

use Sylius\Bundle\ShopBundle\Twig\Component\Cart\FormComponent;
use Sylius\Bundle\UiBundle\Twig\Component\ResourceLivePropTrait;
use Sylius\Bundle\UiBundle\Twig\Component\TemplatePropTrait;
use Sylius\Component\Core\Model\OrderInterface;
use Sylius\Component\Core\Repository\OrderRepositoryInterface;
use Sylius\Component\Order\Context\CartContextInterface;
use Sylius\Component\Order\Context\CartNotFoundException;
use Sylius\Resource\Model\ResourceInterface;
use Sylius\TwigHooks\LiveComponent\HookableLiveComponentTrait;
use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
use Symfony\UX\LiveComponent\Attribute\LiveArg;
use Symfony\UX\LiveComponent\Attribute\LiveListener;
use Symfony\UX\LiveComponent\Attribute\LiveProp;
use Symfony\UX\LiveComponent\DefaultActionTrait;
use Symfony\UX\TwigComponent\Attribute\PreMount;

#[AsLiveComponent]
class WidgetComponent
{
    use DefaultActionTrait;
    use HookableLiveComponentTrait;
    use TemplatePropTrait;

    /** @use ResourceLivePropTrait<OrderInterface> */
    use ResourceLivePropTrait;

    #[LiveProp(hydrateWith: 'hydrateResource', dehydrateWith: 'dehydrateResource')]
    public ?ResourceInterface $cart = null;

    public function __construct(
        protected readonly CartContextInterface $cartContext,
        OrderRepositoryInterface $orderRepository,
    ) {
        $this->initialize($orderRepository);
    }

    #[PreMount]
    public function initializeCart(): void
    {
        $this->cart = $this->getCart();
    }

    #[LiveListener(FormComponent::SYLIUS_SHOP_CART_CHANGED)]
    #[LiveListener(FormComponent::SYLIUS_SHOP_CART_CLEARED)]
    public function refreshCart(#[LiveArg] mixed $cartId = null): void
    {
        // Fix: ignore user-supplied cartId, always load from session
        $this->cart = $this->getCart();
    }

    private function getCart(): ?OrderInterface
    {
        try {
            return $this->cartContext->getCart();
        } catch (CartNotFoundException) {
            return null;
        }

       return $cart;
    }
}

Step 4. Override cart SummaryComponent

Create src/Twig/Components/Cart/SummaryComponent.php:

<?php

declare(strict_types=1);

namespace App\Twig\Components\Cart;

use Sylius\Bundle\ShopBundle\Twig\Component\Cart\FormComponent;
use Sylius\Bundle\UiBundle\Twig\Component\ResourceLivePropTrait;
use Sylius\Bundle\UiBundle\Twig\Component\TemplatePropTrait;
use Sylius\Component\Core\Model\OrderInterface;
use Sylius\Component\Core\Repository\OrderRepositoryInterface;
use Sylius\Resource\Model\ResourceInterface;
use Sylius\TwigHooks\LiveComponent\HookableLiveComponentTrait;
use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
use Symfony\UX\LiveComponent\Attribute\LiveArg;
use Symfony\UX\LiveComponent\Attribute\LiveListener;
use Symfony\UX\LiveComponent\Attribute\LiveProp;
use Symfony\UX\LiveComponent\DefaultActionTrait;

#[AsLiveComponent]
class SummaryComponent
{
    use DefaultActionTrait;
    use HookableLiveComponentTrait;

    /** @use ResourceLivePropTrait<OrderInterface> */
    use ResourceLivePropTrait;
    use TemplatePropTrait;

    #[LiveProp(hydrateWith: 'hydrateResource', dehydrateWith: 'dehydrateResource')]
    public ?ResourceInterface $cart = null;

    /** @param OrderRepositoryInterface<OrderInterface> $orderRepository */
    public function __construct(OrderRepositoryInterface $orderRepository)
    {
        $this->initialize($orderRepository);
    }

    #[LiveListener(FormComponent::SYLIUS_SHOP_CART_CHANGED)]
    public function refreshCart(#[LiveArg] mixed $cartId): void
    {
        // Fix: ignore user-supplied cartId, reload from checksummed cart prop
        if ($this->cart === null) {
            return;
        }

        $this->cart = $this->hydrateResource($this->cart->getId());
    }
}

Step 5. Register overridden services

In config/services.yaml, add:

    sylius_shop.twig.component.checkout.address.form:
        class: App\Twig\Components\Checkout\Address\FormComponent
        arguments:
            $repository: '@sylius.repository.order'
            $formFactory: '@form.factory'
            $resourceClass: '%sylius.model.order.class%'
            $formClass: 'Sylius\Bundle\ShopBundle\Form\Type\Checkout\AddressType'
            $customerContext: '@sylius.context.customer'
            $shopUserRepository: '@sylius.repository.shop_user'
            $addressRepository: '@sylius.repository.address'
        tags:
            - { name: 'sylius.live_component.shop', key: 'sylius_shop:checkout:address:form' }

    sylius_shop.twig.component.cart.widget:
        class: App\Twig\Components\Cart\WidgetComponent
        arguments:
            $cartContext: '@sylius.context.cart.composite'
            $orderRepository: '@sylius.repository.order'
        tags:
            - { name: 'sylius.live_component.shop', key: 'sylius_shop:cart:widget' }

    sylius_shop.twig.component.cart.summary:
        class: App\Twig\Components\Cart\SummaryComponent
        arguments:
            $orderRepository: '@sylius.repository.order'
        tags:
            - { name: 'sylius.live_component.shop', key: 'sylius_shop:cart:summary' }
