Exploited in the wild: not listed in CISA KEV
EPSS: 0.4% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2024-08-08 · updated 2026-06-17
Weakness: CWE-284

Description

Shopware is an open commerce platform. The store-API works with regular entities and not expose all fields for the public API; fields need to be marked as ApiAware in the EntityDefinition. So only ApiAware fields of the EntityDefinition will be encoded to the final JSON. Prior to versions 6.6.5.1 and 6.5.8.13, the processing of the Criteria did not considered ManyToMany associations and so they were not considered properly and the protections didn't get used. This issue cannot be reproduced with the default entities by Shopware, but can be triggered with extensions. Update to Shopware 6.6.5.1 or 6.5.8.13 to receive a patch. For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin.

Affected products

shopware: before 6.5.8.13; from 6.6.0.0 before 6.6.5.1 — fixed in 6.5.8.13, 6.6.5.1

How to fix

Upgrade to a fixed version: shopware 6.5.8.13, 6.6.5.1. Check the vendor advisory for mitigations.
