Is Asciidoctor.js Live Preview safe?

Low risk

Asciidoctor.js Live Preview can send Kroki diagram content and included file data to a document-selected server.

When Kroki rendering is enabled, Asciidoctor.js Live Preview reads diagram includes from the opened document or referenced URLs and sends the resulting diagram text to a Kroki server for rendering. A document can override the configured Kroki server URL, so included content that the extension can read may be sent to a server chosen by that document.

Shared hosts - 8 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
