Nuxt.js Running in Development Mode
Description
The Nuxt.js application is configured to run in development mode on a production server. Development mode enables verbose error reporting, detailed stack traces, source code exposure, and debugging features that are intended only for local development environments. These features significantly increase the attack surface by revealing internal application structure, file paths, dependency versions, and configuration details that attackers can leverage to identify and exploit vulnerabilities more effectively.
Remediation
Configure your Nuxt.js application to run in production mode before deploying to any live environment. Follow these steps to remediate this issue:
1. Set the NODE_ENV environment variable:
Ensure that NODE_ENV is set to production in your deployment environment. This can be configured in your hosting platform, container orchestration system, or deployment scripts.
export NODE_ENV=production node server/index.js
2. Verify Nuxt configuration:
In your nuxt.config.js file, ensure the dev property is not hardcoded to true. The framework should automatically detect production mode from NODE_ENV:
export default {
// Do not set dev: true in production
// Let Nuxt detect mode from NODE_ENV
}3. Build for production:
Always run a production build before deployment:
npm run build npm run start
4. Validate the configuration:
After deployment, verify that development mode is disabled by checking that detailed error pages and stack traces are not displayed when errors occur.
