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?
Gemfile
Ruby Gem Dependencies
What an attacker could do
Reveals exact Ruby gem dependencies and version constraints, letting an attacker cross-reference known CVEs (e.g. vulnerable Rails, Nokogiri, or Devise releases) to craft targeted exploits.
How to defend it
Keep Gemfile and Gemfile.lock outside the web-served document root, and block requests for them at the web server or CDN so they return 404.
