Information Disclosure in typo3/cms-install tool

  • Disclosed: 14.11.2023
  • Updated: 11.10.2026 10:22

CVSS: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:F/RL:O/RC:C (3.5)

Problem

The login screen of the standalone install tool discloses the full path of the transient data directory (e.g. /var/www/html/var/transient/). This applies to composer-based scenarios only - “classic” non-composer installations are not affected.

Solution

Update to TYPO3 version 12.4.8 that fixes the problem described above.
