CVE-2021-32720

Sylius is an Open Source eCommerce platform on top of Symfony.

Sylius is an Open Source eCommerce platform on top of Symfony. In versions of Sylius prior to 1.9.5 and 1.10.0-RC.1, part of the details (order ID, order number, items total, and token value) of all placed orders were exposed to unauthorized users. If exploited properly, a few additional information like the number of items in the cart and the date of the shipping may be fetched as well. This data seems to not be crucial nor is personal data, however, could be used for sociotechnical attacks or may expose a few details about shop condition to the third parties. The data possible to aggregate are the number of processed orders or their value in the moment of time. The problem has been patched at Sylius 1.9.5 and 1.10.0-RC.1. There are a few workarounds for the vulnerability. The first possible solution is to hide the problematic endpoints behind the firewall from not logged in users. This would put only the order list under the firewall and allow only authorized users to access it. Once a user is authorized, it will have access to theirs orders only. The second possible solution is to decorate the `\Sylius\Bundle\ApiBundle\Doctrine\QueryCollectionExtension\OrdersByLoggedInUserExtens

How likely is an attack? The Exploit Prediction Scoring System, run by FIRST (the global association of security response teams), puts the odds of this one being exploited in the next 30 days at 0.88%, higher than 58% of CVEs. That’s low, but low isn’t zero, and the odds jump the day someone publishes an exploit. Scored October 28, 2026, updated daily.

Check your own setup

  • Website check: reads what your site runs from the outside (WordPress version, plugins it can see, old server software) and matches it against this database.
  • Server check: what your web server says about itself, and whether that version has known flaws.
