npm symlink reference outside of node_modules
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
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 the`node_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.
