Cross-Site Scripting (XSS) Prevention

Modern DevSecOps (The Hard Way)

Sanitize Your Inputs

XSS happens when malicious scripts are injected into trusted websites.

DevSecOps Approach:

  1. Content Security Policy (CSP): Configure headers in your YAML/Nginx config to restrict where scripts can be loaded from.
  2. SAST: Use Semgrep to find places where user input is rendered without escaping.
