CVE-2025-59016Network attack vector

Full-path disclosure via unsuppressed filesystem warnings

Published Sep 9, 2025 · Updated Sep 9, 2025

Information disclosure in TYPO3 CMS allows remote authenticated users to read full server paths through failed file operations. File Abstraction Layer LocalDriver methods call PHP filesystem functions without suppressing E_WARNING output, which TYPO3's error handler converts into exceptions containing absolute resource paths. A valid backend account and a failed low-level filesystem operation are required; the disclosed paths reveal installation layout but do not modify files or interrupt service.
