Hi,

The following vulnerabilities were published for npm.

CVE-2019-16775[0]:
| Versions of the npm CLI prior to 6.13.3 are vulnerable to an Arbitrary
| File Write. It is possible for packages to create symlinks to files
| outside of thenode_modules folder through the bin field upon
| installation. A properly constructed entry in the package.json bin
| field would allow a package publisher to create a symlink pointing 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.


CVE-2019-16776[1]:
| 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.


CVE-2019-16777[2]:
| 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.
