Summary

Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, a non-admin API user with integration:create ACL privilege can escalate to full administrator by creating an integration with admin: true through the Sync API POST /api/_action/sync; the regular integration endpoint POST /api/integration blocks this, but SyncController::sync() routes writes through SyncService to EntityWriter::upsert(), and src/Core/Framework/Integration/IntegrationDefinition.php lacks WriteProtection on the admin field. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.
