What to fix

1. Add a Content-Security-Policy
   Limits which scripts can run, and is the main defense against XSS. Start with Content-Security-Policy-Report-Only to test.
2. Add X-Content-Type-Options
   Header: X-Content-Type-Options: nosniff
3. Prevent clickjacking
   Header: X-Frame-Options: DENY (or a CSP frame-ancestors directive).
4. Add a Referrer-Policy
   Header: Referrer-Policy: strict-origin-when-cross-origin
5. Publish a DMARC record
   A TXT record at _dmarc.<domain>; start with v=DMARC1; p=none; to monitor.
