Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

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.
