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?
user-data
Cloud-init user-data path that can contain bootstrap scripts and secrets
What an attacker could do
Cloud-init user-data frequently contains bootstrap scripts with embedded secrets, SSH keys, or credentials; retrieval (e.g., via SSRF to the metadata endpoint) hands an attacker instance provisioning details.
How to defend it
Avoid embedding secrets in user-data, enforce IMDSv2 to block SSRF-based metadata access, and never expose cloud-init artifacts through the web server.
