Summary
npm symlink reference outside of node_modules
Details
Versions of the npm CLI prior to 6.13.3 are vulnerable to a symlink reference outside of node_modules. 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. Only files accessible by the user running the npm install
are affected.
This behavior is still possible through install scripts. This vulnerability bypasses a user using the --ignore-scripts install option.
Recommendation
Upgrade to version 6.13.3 or later.
