### Summary The `WordExport` export flow only checks whether the current backend user has the feature permission `word_export`. It does not verify access rights on the target element itself. As a result, a low-privileged backend user can export document content even when the user does not have `view` permission on that document. In the local Docker reproduction, a low-privileged user successfully exported sensitive content from a page the user was not allowed to view: - `POC-WORDEXPORT-TITLE` - `POC-WORDEXPORT-DESC` ### Root Cause The controller only performs a feature-level permission check before starting the export flow: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L41)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L44)#L41) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L56)#L44) It then directly resolves the target element from attacker-controlled `type/id` input: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L58)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L56) - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L72)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L113)#L58) For document-like elements such as `Page` and `Snippet`, it renders content in an admin context: - [[TranslationController.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L114)](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L72) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L113) - [TranslationController.php](pimcore-12.3.3/bundles/WordExportBundle/src/Controller/TranslationController.php#L114) No object-level authorization check such as `isAllowed('view')` is enforced on the target element. ### Affected Scope Based on the source code, the following element types may be affected: - `page` - `snippet` - `email` - `object` For page-like documents, the `pimcore_admin = true` rendering context may expose additional backend-visible content. ### Preconditions - The attacker is an authenticated backend user - The attacker has the `word_export` permission - The attacker does not have `view` permission on the target document ### Reproduction Environment - Reproduction root: `pimcore-12.3.3-repro` - Standalone PoC script: [[poc_wordexport.php](https://github.com/pimcore/pimcore/security/advisories/pimcore-12.3.3-repro/tools/poc_wordexport.php)](pimcore-12.3.3-repro/tools/poc_wordexport.php) ```php <?php declare(strict_types=1); use Pimcore\Bundle\WordExportBundle\Controller\TranslationController as WordExportController; use Pimcore\Controller\UserAwareController; use Pimcore\Model\Document\Page; use Pimcore\Model\User; use Pimcore\Security\User\TokenStorageUserResolver; use Pimcore\Security\User\User as SecurityUser; use Pimcore\Serializer\Serializer as PimcoreSerializer; use Pimcore\Tool\Authentication; use Symfony\Component\DependencyInjection\ContainerInterface; use Symfony\Component\Filesystem\Filesystem; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\RequestStack; use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken; use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage; require dirname(__DIR__) .
