CVE-2019-16776
Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary File Write.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.41%). 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.
