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

Shopware vulnerable to Server Side Template Injection in Twig using Context functions
The `context` variable is injected into almost any Twig Template and allows to access to current language, currency information. The context object allows also to switch for a short time the scope of the Context as a helper with a callable function.

Example call from PHP:

```php
$context->scope(Context::SYSTEM_SCOPE, static function (Context $context) use ($mediaService, $media, &$fileBlob): void {
$fileBlob = $mediaService->loadFile($media->getId(), $context);
});
```

This function can be called also from Twig and as the second parameter allows any callable, it's possible to call from Twig any statically callable PHP function/method.

It's not possible as customer to provide any Twig code, the attacker would require access to Administration to exploit it using Mail templates or using App Scripts.

Shopware vulnerable to blind SQL-injection in DAL aggregations
The Shopware application API contains a search functionality which enables users to search through information stored within their Shopware instance. The searches performed by this function can be aggregated using the parameters in the “aggregations”
object. The ‘name’ field in this “aggregations” object is vulnerable SQL-injection and can be exploited using SQL parameters.

Shopware vulnerable to Server Side Template Injection in Twig using deprecation silence tag
Shopware has a new Twig Tag `sw_silent_feature_call` which silences deprecation messages while triggered in this tag.
It accepts as parameter a string the feature flag name to silence, but this parameter is not escaped properly and allows execution of code.
