All versions of larvitbase-www are vulnerable to an Unintended Require. The package exposes an API endpoint and passes a GET parameter unsanitized to an require() call. This allows attackers to execute any .js file in the same folder as the server is running.

Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
