Improper authorization control for web services In shopware/core

Description

Shopware vulnerable to Improper Access Control with ManyToMany associations in store-api

Impact

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.

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.

Patches

Update to Shopware 6.6.5.1 or 6.5.8.13.

Workarounds

For older versions of 6.2, 6.3, and 6.4, corresponding security measures are also available via a plugin. For the full range of functions, we recommend updating to the latest Shopware version.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
