Is Avaya Cloud Office for Google safe?

Low risk

Avaya Cloud Office for Google lets allowed web pages queue click-to-dial or text actions through a broad message bridge.

The content script runs on most HTTP and HTTPS pages and accepts postMessage events on a hardcoded Avaya channel without checking the sender origin. A non-blocklisted page can supply phone numbers that the extension stores as click-to-call or text actions, along with the page's domain, when the user is logged in and C2D permissions are enabled.

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

Shared hosts - 2 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.
