Is Imagus mod safe?

Medium risk

Imagus mod runs auto-updated remote sieve rules as code on every site.

The extension injects content scripts on all pages and automatically fetches sieve rules from a GitHub-hosted update file. Those rule bodies can be compiled with Function and executed during image-preview resolution, giving the remotely updated rules access to the page URL and DOM content.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

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.
