CVE-2026-49742

TYPO3 CMS - Broken Access Control in Media Module

State: Published
Severity: 7.1 High
Published: Jun 9, 2026
Updated: Jun 11, 2026
Reserved: Jun 1, 2026

Description

Backend users with file download permissions were able to download files from the fallback storage of the file abstraction layer (FAL) via the Media Module. Since the fallback storage resolves paths relative to the server's document root, this could expose sensitive files such as log files. This issue affects TYPO3 CMS versions 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.
