Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

app.js

Common Node.js/Express application entry-point file

What an attacker could do

If the raw file is served instead of executed, it discloses Node.js/Express application source, revealing routes, middleware, database connection logic, and possibly hardcoded credentials.

How to defend it

Ensure the application server runs the code rather than the web server serving it, keep source outside any static document root, and store secrets in environment variables.
