Optional DNS validation is disabled by default and, when enabled, only confirms a DNS record exists without filtering by IP range. The fetch response body is returned to the requester only when the Content-Type matches an ActivityPub content type, making this a semi-blind but authenticated SSRF primitive reachable by any logged-in user.
