Details

Problem

Backend users were able to insert arbitrary records and files into the TYPO3 clipboard without proper read permission checks, which allowed users to gather information about records and files they were not authorized to view.

Solution

Update to TYPO3 versions 10.4.57 ELTS, 11.5.51 ELTS, 12.4.46 ELTS, 13.4.31 LTS, 14.3.3 LTS that fix the problem described.

TYPO3 CMS thanks Vincent Yang for reporting this issue, and to TYPO3 security team member Elias Häußler for fixing it.

Is GHSA-q93m-25xv-94hh in any of your client repos?

Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected typo3/cms-core, and gives you the command that fixes it.

Scan a project free, no signup Or connect GitHub to scan every repo
