## Technical details

A missing authorization vulnerability (CWE-862) exists in the WordExportBundle of Pimcore. The TranslationController.php component performs a feature-level check for 'word_export' permissions but fails to verify object-level 'view' permissions on the specific elements being exported. An authenticated backend user can provide arbitrary 'type' and 'id' parameters to the export flow to bypass access controls on pages, snippets, emails, and objects. This allows the extraction of sensitive content that would otherwise be restricted via the standard administrative interface. The vulnerability is resolved in Pimcore versions 11.5.17 (LTS) and 12.3.7 by enforcing isAllowed('view') checks on target elements.
