Comment 1 TomasJuhasz 2026-02-24 19:17:01 UTC
We determined that this vulnerability can not be exploited in our products, as npm have additional protection against all links while using node-tar.

Here is upstream npm bugs that are both closed with same explanation(not affected):
https://github.com/npm/cli/issues/8922
https://github.com/npm/cli/issues/8917

Additionally here is part of npm source code that does said protection:
https://github.com/npm/cli/blob/f8d25cd00132c8c7798a3f982a8da38ceed81e6b/node_modules/pacote/lib/fetcher.js#L421
