How to fix?

There is no fix version for mongoosemask.


mongoosemask is an Express Middleware to filter out Mongoose model attributes.

Affected versions of the package are vulnerable to Arbitrary Code Injection due to unsafe use of the eval() function. Node.js provides the eval() function by default, and is used to translate strings into Javascript code. An attacker can craft a malicious payload to inject arbitrary commands.
