CVE-2026-49742: TYPO3 CMS

High severity, CVSS 7.1. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• TYPO3 TYPO3 CMS: from 11.0.0, before 11.5.51 (fixed in 11.5.51); from 12.0.0, before 12.4.46 (fixed in 12.4.46); from 13.0.0, before 13.4.31 (fixed in 13.4.31); from 14.0.0, before 14.3.3 (fixed in 14.3.3)
