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?

config/secrets.yml

Rails Secrets Configuration

What an attacker could do

Exposure leaks the Rails secret_key_base and other tokens, letting an attacker forge and tamper with signed session cookies, which can escalate to authentication bypass or deserialization-based RCE.

How to defend it

Migrate to Rails encrypted credentials, keep secrets in environment variables, and confirm the config/ directory is never inside the public document root.
