{"id":"GHSA-v39m-97p8-gqg7","summary":"Shopware: Privilege escalation: non-admin user with user:create ACL can create admin accounts","details":"`UserController::upsertUser()` writes user data in `SYSTEM_SCOPE` and does not filter the `admin` field. A non-admin API user with `user:create` or `user:update` ACL permission can set `admin: true` on new or existing users, escalating to full admin access.\n\n## The Problem\n\nIn `src/Core/Framework/Api/Controller/UserController.php`, line 210-234:\n\n```php\npublic function upsertUser(?string $userId, Request $request, Context $context, ResponseFactoryInterface $factory): Response\n{\n    $data = $request-\u003erequest-\u003eall(); // raw request data, no field filtering\n    // ...\n    $events = $context-\u003escope(Context::SYSTEM_SCOPE, fn (Context $context) =\u003e\n        $this-\u003euserRepository-\u003eupsert([$data], $context)\n    );\n}\n```\n\n`SYSTEM_SCOPE` bypasses `AclWriteValidator` entirely (line 52 of `AclWriteValidator::preValidate()` returns early for `SYSTEM_SCOPE`). The `admin` boolean field is accepted without restriction.\n\nCompare with `IntegrationController::upsertIntegration()` in the same codebase, which correctly checks:\n\n```php\nif ((!$source instanceof AdminApiSource)\n    || (!$source-\u003eisAdmin()\n    && isset($data['admin']))\n) {\n    throw new PermissionDeniedException();\n}\n```\n\n`UserController` is missing this exact check.\n\n## Impact\n\nAny API user with the low-privilege `user:create` permission can create accounts with full admin access, or with `user:update` can promote any existing user to admin. This is a direct privilege escalation.\n\n## Suggested Fix\n\nAdd the same `isAdmin()` check from `IntegrationController`:\n\n```php\n$source = $context-\u003egetSource();\nif ((!$source instanceof AdminApiSource) || (!$source-\u003eisAdmin() && isset($data['admin']))) {\n    throw new PermissionDeniedException();\n}\n```\n\nBest regards,\nKeyvan
