Before jumping into the final post within our discussion on vulnerabilities in the MEAN stack, look back at the other four posts within this series discussing MongoDB, Express.js (Core), Express.js (Sessions and CSRF), and AngularJS.
Development mode (Node.js/Express.js)
By default, Express applications run in development mode unless the NODE_ENV environmental variable is set to another value. In development mode, Express returns more verbose errors which can result in information leakage. For example, the error message below returns the full path to the requested file. This also provides an attacker with information about the host system.
