CVE-2026-31819 (opens in a new tab)How to fix?
Upgrade sylius/sylius to version 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 or higher.
Overview
sylius/sylius is a platform for PHP, based on Symfony framework.
Affected versions of this package are vulnerable to Open Redirect in the handling of the switchAction, impersonateAction, and handle processes when redirecting users based on the HTTP Referer header. An attacker can redirect users to malicious external sites by enticing them to click crafted links, potentially leading to phishing or credential theft. This is only exploitable if a user or administrator follows a link from an attacker-controlled page or external source such as email or chat.
Workaround
This vulnerability can be mitigated by copying the affected classes to your project's source directory, applying the provided fixes to avoid using the Referer header for redirects, and overriding the relevant service definitions in your configuration.
