An uncaught exception in the Bookmark Toolbar of TYPO3 CMS versions 11.0.0–11.5.47, 12.0.0–12.4.36, and 13.0.0–13.4.17 lets administrator‑level backend users trigger a denial‑of‑service condition in the backend user interface by saving manipulated data in the bookmark toolbar.
Is GHSA-xrcq-533q-8rxw 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.
