Top issues to fix

    Add a CSP to control which sources can run scripts — the strongest single defense against XSS.

    Add X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.

    Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.

  • 1 cookie without Secure/HttpOnly flags

    Set Secure and HttpOnly on session cookies so they can't leak over HTTP or be read by injected scripts.

  • robots.txt not found
