Background
express-mock-middleware is an npm package that provides mock middleware for the Express.js framework. It allows developers to simulate API responses during development and testing. The package is vulnerable to Prototype Pollution, a type of vulnerability where properties of the Object.prototype can be modified or added. This vulnerability can be exploited by tricking the package into adding or modifying properties of the Object.prototype. The impact of this vulnerability is considered to be low, as it requires the creation of a new directory and the placement of attack code that will be exported by express-mock-middleware.
