TYPO3-CORE-SA-2025-023: Information Disclosure via CSV Download

Categories: Development, TYPO3 CMS Created by Oliver Hader
It has been discovered that TYPO3 CMS is susceptible to information disclosure.


Problem Description

The CSV download feature in the backend user interface allowed callers to request arbitrary data from the database without performing a permission check on the target table. Consequently, a backend user without rights to a particular database table could retrieve records, leading to information disclosure. This vulnerability was limited to database records that fell within the page tree the user was already permitted to access.

Solution

Update to TYPO3 versions 11.5.48 ELTS, 12.4.37 LTS, 13.4.18 LTS that fix the problem described.

Credits
