CVE-2019-16776

Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write.

HIGH 8.1EPSS 3.42%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
