Details

Problem

Due to insufficient input validation, manipulated data saved in the bookmark toolbar of the backend user interface causes a general error state, blocking further access to the interface. Exploiting this vulnerability requires an administrator-level backend user account.

Solution

Update to TYPO3 versions 10.4.46 ELTS, 11.5.40 LTS, 12.4.21 LTS, 13.3.1 that fix the problem described.

Is GHSA-ffcv-v6pw-qhrp 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-backend, and gives you the command that fixes it.
