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.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
shopware/core to 6.7.8.1 or later; shopware/core to 6.6.10.15 or later; shopware/platform to 6.7.8.1 or later; shopware/platform to 6.6.10.15 or later
Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2026-31887? CVE-2026-31887 is a high-severity incorrect authorization vulnerability in shopware/core (composer), affecting versions >= 6.7.0.0, < 6.7.8.1. It is fixed in 6.7.8.1, 6.6.10.15. The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions.
- Which packages are affected by CVE-2026-31887?
shopware/core(composer) (versions >= 6.7.0.0, < 6.7.8.1)shopware/platform(composer) (versions >= 6.7.0.0, < 6.7.8.1)
- Is there a fix for CVE-2026-31887? Yes. CVE-2026-31887 is fixed in 6.7.8.1, 6.6.10.15. Upgrade to this version or later.
- Is CVE-2026-31887 exploitable, and should I be worried? Whether CVE-2026-31887 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-31887 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
