CVE-2019-16777 (GCVE-0-2019-16777)

Vulnerability from cvelistv5 – Published: 2019-12-13 01:00 – Updated: 2024-08-05 01:24
VLAI?
Summary
Versions of the npm CLI prior to 6.13.4 are vulnerable to an Arbitrary File Overwrite. It fails to prevent existing globally-installed binaries to be overwritten by other package installations. For example, if a package was installed globally and created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the previous serve binary. This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
