Affected versions of this package are vulnerable to Missing Authorization via the plugin autoloading process. An attacker can execute arbitrary code by leveraging the automatic execution of Yarn plugins before the user accepts the risks associated with an untrusted directory. This is only exploitable if Yarn versions 2.0+ are used, as Yarn Classic is not affected.
