Is Ezoic safe?

Low risk

Ezoic lets any website that frames its Humix page update Ezoic video settings through videoapi.ezoic.com.

When a site loads the web-accessible Humix page in an iframe, that page accepts postMessage commands without checking the sender and can change the saved universal-player location for the active Ezoic domain. The change is then sent to videoapi.ezoic.com using the browser's Ezoic session cookies.

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.

What it can do

Permissions this extension asks for, as declared in version 4.2.28. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data

Destinations our analysis observed Ezoic 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.

  • videoapi.ezoic.com

    Ezoic sends data to videoapi.ezoic.com. No other extension we have analysed sends data here.
