| Package | Affected versions | Patched versions |
|---|---|---|
| npm | < 6.13.3 | 6.13.3 |
| graalvm | = 19.3.0.2 | |
| npm | < 6.13.3 | 6.13.3 |
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.
Upgrade to version 6.13.3 or later.
