Is Capital Koala safe?

Medium risk

Capital Koala sends login credentials to its API with the password embedded in the request URL.

When a user signs in through the extension, its login flow builds a GET request to www.capitalkoala.com/api/auth/login_v2/ with both login and password values in the query string. The endpoint is a first-party Capital Koala service over HTTPS, but the password is still serialized into the URL rather than sent in a POST body.

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.

Where it sends data

Destinations our analysis observed Capital Koala 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.
