Authorization Flaw in pimcore/pimcore (CVE-2026-45703)
Summary
Vulnerability in pimcore/pimcore (CVE-2026-45703). Risk of unauthorized operations or information disclosure. Exploitable via WordExport. Mitigation: upgrade to 2026.1.3 or later.
Original description
The description as published by the source.
Pimcore is an Open Source Data & Experience Management Platform. Prior to 11.5.17 (LTS) and 12.3.7, the WordExport export flow in bundles/WordExportBundle/src/Controller/TranslationController.php only checks the word_export feature permission and directly resolves attacker-controlled type/id input without enforcing view permission on page, snippet, email, or object elements, allowing a low-privileged backend user to export document content the user is not allowed to view. This issue is fixed in versions 11.5.17 (LTS) and 12.3.7.
