CWE-22

Description

Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write. It fails to prevent access to folders outside of the intended node_modules folder through the bin field. A properly constructed entry in the package.json bin field would allow a package publisher to modify and/or gain access 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

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