CVE-2024-34355Network attack vector

HTML injection via raw history record titles

Published May 14, 2024 · Updated Aug 2, 2024

HTML injection in TYPO3 CMS 13.0.0 through 13.1.0 allows remote authenticated users to place malicious markup in backend history views. The History.html template renders the title returned by BackendUtility::getRecordTitle as raw output even when that value was not HTML-encoded. A valid backend account and another user's viewing of the affected history entry are required; Content Security Policy prevents JavaScript execution, limiting impact to displayed markup.
