Is WebTerminal safe?

Clean risk

WebTerminal fetches user-installed cmdhub packages from GitHub and injects their JavaScript into HTTP(S) pages.

When a user installs a cmdhub command, WebTerminal downloads cmd.json and the referenced script from raw.githubusercontent.com, then stores that script in browser storage. On HTTP(S) page loads, it can run the stored command code in tabs covered by its all-URLs permissions, giving the injected command access to page URLs and DOM content.

Where it sends data

Destinations our analysis observed WebTerminal 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.
