CVE-2026-77132Network attack vector

Restricted metadata disclosure via unchecked localization routes

Published Sep 8, 2026 · Updated Sep 8, 2026

Missing authorization in TYPO3 CMS 10.0.0 through 14.3.6 allows remote authenticated users to read restricted content metadata. The getUsedLanguagesInPage() and getRecordLocalizeSummary() AJAX endpoints accept a page ID and return languages, record titles, UIDs, and backend-layout columns without checking PAGE_SHOW access. A low-privileged backend account with page-module access is required; disclosure is limited to metadata for pages outside that account's permitted range.
