Description

Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It is possible for packages to create symlinks to files outside of thenode_modules folder through the bin field upon installation. A properly constructed entry in the package.json bin field would allow a package publisher to create a symlink pointing to arbitrary files on a user's system when the package is installed. This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.

Affected configurations

• redhat enterprise linux 8.0 • redhat enterprise linux eus 8.1 • npmjs npm (< 6.13.3) • opensuse leap 15.1 • oracle graalvm 19.3.0.2 • oracle graalvm 20.3.3 • oracle graalvm 21.2.2 • fedoraproject fedora 31
