2024-06-01 - [Missing Security Headers]

Vulnerability: The web application served by Caddy was missing essential security headers, making it more vulnerable to Clickjacking and MIME-sniffing attacks. Learning: Security headers should be explicitly configured in the reverse proxy/web server (Caddy in this case) since they are not typically added by default application servers or front-end frameworks. Prevention: Always ensure standard security headers (X-Frame-Options, X-Content-Type-Options, Referrer-Policy, etc.) are configured globally in the Caddyfile or equivalent web server configuration for all incoming requests.
