Global node_modules Binary Overwrite in npm

low severity Published Dec 13, 2019 in npm/cli • Updated Jan 8, 2021

Package

npm npm (npm)

Affected versions

< 6.13.4

Patched versions

6.13.4

Description

Versions of the npm CLI prior to 6.13.4 are vulnerable to a Global node_modules Binary 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 first binary. This will not overwrite system binaries but only binaries put into the global node_modules directory.

This behavior is still allowed in local installations and also through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.

Recommendation

Upgrade to version 6.13.4 or later.
