Affected versions of this package are vulnerable to Arbitrary File Overwrite. It is possible for a malicious package, upon install, to write to any path on the filesystem even when the --ignore-scripts option is set. This occurs due to symlinks not being correctly unpacked as part of the Yarn install process.

How to fix Arbitrary File Overwrite?
