Is Synology Image Assistant Extension safe?
Synology Image Assistant Extension exposes a native-messaging file-upload bridge to any web page via an unguarded postMessage handler.
The extension injects a content script into every page that listens for postMessage events without checking the sender's origin. Any web page can send a message with the type 'synofoto_init_port' to obtain a MessagePort, then issue commands including thumbnail retrieval, video slice transmission, and file upload—all relayed through the extension to the local Synology desktop client via native messaging. The native messaging host contacted is com.synology.extension.host, which communicates with the Synology Photos desktop application over a local Socket.IO websocket.

Same store account
3 other listings published from this account, 180k+ users between them, none of them carrying a finding.
Shared hosts - 3 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.

Where it sends data
Destinations our analysis observed Synology Image Assistant contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
