Description

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.

Affected configurations

• npmjs npm (< 6.13.4) • opensuse leap 15.1 • oracle graalvm 19.3.0.2 • fedoraproject fedora 31 • redhat enterprise linux 8.0 • redhat enterprise linux eus 8.1
