MEDIUMPre-NVD 6.46.4—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 91% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
