CVE-2019-16776 (GCVE-0-2019-16776)

Vulnerability from cvelistv5 – Published: 2019-12-13 00:55 – Updated: 2024-08-05 01:24
VLAI?
Summary
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.
