Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Periodic review and update of procedures reduces incorrect authorization implementations over time.
Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.
Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.
Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.
Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.
Ensures authorization decisions for external system use are correctly implemented and enforced.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?

Deeper analysisAI
CVE-2026-31887 is a vulnerability in Shopware, an open commerce platform, affecting versions prior to 6.7.8.1 and 6.6.10.15. It arises from an insufficient check on filter types for unauthenticated customers within the deepLinkCode support on the store-api.order endpoint, enabling access to orders belonging to other customers. The issue, published on 2026-03-11, carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and maps to CWE-863 (Incorrect Authorization).
Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction. By manipulating filter types on the affected endpoint, they can retrieve sensitive order data from other customers, achieving high confidentiality impact while leaving integrity and availability unaffected.
The official Shopware security advisory (https://github.com/shopware/shopware/security/advisories/GHSA-7vvp-j573-5584) confirms the vulnerability and states it is fixed in versions 6.7.8.1 and 6.6.10.15. Security practitioners should prioritize upgrading affected Shopware instances to these patched releases to prevent unauthorized order data exposure.
