GHSA-35jp-8cgg-p4wj

Shopware vulnerable to Server Side Template Injection in Twig using Context functions

Quick fix

GHSA-35jp-8cgg-p4wj — shopware/core: upgrade to the fixed version with the command below.

composer require shopware/core:^6.5.8.13

Details

### Impact 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.

### Patches Update to Shopware 6.6.5.1 or 6.5.8.13

### Workarounds For older versions of 6.1, 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.
