Priority fixes for tempmail.ninja
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
Why it matters: Without it, another site can load your pages in a hidden frame and trick visitors into clicking buttons (clickjacking).
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
On Cloudflare: Add the header with a response header transform rule.
76% of Webmail & Message Inboxes peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.
42% of Webmail & Message Inboxes peers do this.

Priority 3 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for tempmail.ninja, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.
33% of Webmail & Message Inboxes peers do this.
Priority 4 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.
20% of Webmail & Message Inboxes peers do this.
