Shopware: Unauthenticated data extraction possible through store-api.order endpoint

CVE-2026-31887GHSA-7vvp-j573-5584

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (shopware/core 6.7.8.1, 6.6.10.15; shopware/platform 6.7.8.1, 6.6.10.15), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2026-31887

Advisory: Shopware: Unauthenticated data extraction possible through store-api.order endpoint
IDs: CVE-2026-31887, GHSA-7vvp-j573-5584
Record: https://patchnext.com/advisories/cve-2026-31887 (revision 1, source checked 26 Oct 2026, 14:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: shopware/core 6.7.8.1, 6.6.10.15; shopware/platform 6.7.8.1, 6.6.10.15. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist shopware/core: affected >= 6.7.0.0, < 6.7.8.1; < 6.6.10.15; fixed in 6.6.10.15, 6.7.8.1
- Packagist shopware/platform: affected >= 6.7.0.0, < 6.7.8.1; < 6.6.10.15; fixed in 6.6.10.15, 6.7.8.1

## Suggested inspection (read-only)
- Packagist shopware/core: check the installed version with your package manager.
- Packagist shopware/platform: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on shopware/core, shopware/platform.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
