Server-Side Request Forgery (SSRF) & Supply Chain Security

Identify SSRF risks, block internal IP metadata endpoints (169.254.169.254), and audit open-source dependency vulnerabilities.

SSRF Attack Vector Mechanics

### What is SSRF? Server-Side Request Forgery (SSRF) occurs when a web server fetches data from a user-supplied URL without validating the destination IP. Attackers abuse SSRF to query internal microservices or cloud instance metadata endpoints (`http://169.254.169.254/`).
