CVE-2019-16776

Unauthorized File Access in npm CLI before before version 6.13.3

Published Dec 13, 2019 CVSS 3.1 · 7.7 High EPSS 3.4% KEV · Not listed
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.
