shopware/core fixed: 6.7.8.1 
Upgrade shopware/core to 6.7.8.1
shopware/core fixed: 6.6.10.15 
Upgrade shopware/core to 6.6.10.15
shopware/platform fixed: 6.7.8.1 
Upgrade shopware/platform to 6.7.8.1
shopware/platform fixed: 6.6.10.15 
Upgrade shopware/platform to 6.6.10.15
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/core

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-31887, inspect your project dependencies for Shopware:

inspect dependencies for shopware/core

Analyze the terminal output to locate any version of Shopware in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 6.7.8.1), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. In Shopware, 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

### Summary An insufficient check on the filter types for unauthenticated customers allows access to orders of other customers. This is part of the `deepLinkCode` support on the `store-api.order` endpoint. ### Details #### Data Exposure Depending on the order payload configuration, attackers may retrieve: - Customer names - Billing address - Shipping address - Email addresses - Ordered products - Order values - Order numbers - Order dates - Payment method information - Shipping method information - More customs, depending on the given associations in the request #### Security Impact This vulnerability allows: - Unauthorized access to foreign customer order data - Mass enumeration of recent orders - Potential scraping of customer personal information #### Limitation No limitation, but only orders from the past 30 days are checked for changeable means of payment (unrelated). ### Impact The code is present since ~2021. Likely every version since then is impacted for every store.
