What to fix

Add Strict-Transport-Security
Header: Strict-Transport-Security: max-age=31536000; includeSubDomains
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.
Add X-Content-Type-Options
Header: X-Content-Type-Options: nosniff
Prevent clickjacking
Header: X-Frame-Options: DENY (or a CSP frame-ancestors directive).
Add a Referrer-Policy
Header: Referrer-Policy: strict-origin-when-cross-origin
