Shodan matched these CVEs against the service banners it saw on 162.209.113.154 (authorsguild.net), which advertise http server 2.4.62, openssl 3.5.1. These are version-fingerprint matches, not confirmed exploits: a distribution may have back-ported the fix while leaving the banner unchanged. Severity reflects the volume of known issues associated with this host, not a CVSS score.

What to do
Confirm the running versions on 162.209.113.154 and compare them against the current security release for each package before treating any single CVE as live.

SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.authorsguild.net TXT "v=DMARC1; p=none; rua=mailto:dmarc@authorsguild.net"`, review the reports, then move to p=quarantine and p=reject.
asset: authorsguild.net
162.209.113.154 (authorsguild.net) reports http server 2.4.62, openssl 3.5.1. Publishing precise versions lets anyone match the host against a CVE feed without probing it, which is how targets get shortlisted for mass exploitation after a new advisory lands.
What to do
Suppress version tokens in server banners (for example `ServerTokens Prod` in Apache) and keep the packages current.
asset: 162.209.113.154
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://authorsguild.org/web-services/
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://authorsguild.org/web-services/
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://authorsguild.org/web-services/
Exact versions in response headers let anyone match the server against a CVE feed without touching it.
What to do
Strip version tokens (`ServerTokens Prod`, `server_tokens off`, remove X-Powered-By).
asset: https://authorsguild.org/web-services/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: authorsguild.net
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: authorsguild.net
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
