Synopsis

Next.js Configuration File Detected

Description

Next.js is a popular React framework for building web applications. By default, Next.js applications may include a configuration file named next.config.js, which contains various settings and options for the application. If this configuration file is accessible via the web server, it can expose sensitive information about the application's structure, environment variables, and other configurations that could be exploited by attackers.

Solution

Ensure that the configuration file is not deployed with the application or, at least, is not exposed in a web server directory by setting proper permissions on it.
