shopware/core fixed: 6.4.18.1 
Upgrade shopware/core to 6.4.18.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for shopware/platform

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-22731, inspect your project dependencies for Shopware/platform:

inspect dependencies for shopware/platform

Analyze the terminal output to locate any version of Shopware/platform in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.4.18.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Shopware/platform, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In Twig environment **without the Sandbox extension**, it is possible to refer to PHP functions in twig filters like `map`, `filter`, `sort`. This allows in the template to call any global PHP function. ### Patches The problem has been fixed with 6.4.18.1 with an override of the specified filters until the integration of the Sandbox extension has been finished. ### Workarounds For older versions of 6.1, 6.2, and 6.3, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version. ### References https://docs.shopware.com/en/shopware-6-en/security-updates/security-update-01-2023?category=security-updates
