Is Vendoo Crosslist Extension v3 safe?

Clean risk

Vendoo Crosslist Extension automates listing across resale marketplaces by polling its servers for commands and executing them in browser tabs.

The extension connects to api.web.vendoo.co every five minutes to receive automation instructions from Vendoo's back end. These commands can read cookies from supported marketplace sites (Facebook, Mercari, Poshmark, Depop, Grailed, and others), perform click and form-fill sequences in browser tabs, make network requests on the user's behalf, and capture outgoing POST request bodies on Facebook pages. All results are returned to Vendoo's servers to complete crosslisting and inventory-management workflows.

Shared hosts - 4 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 Vendoo 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.

  • api.web.vendoo.co

    Vendoo sends data to api.web.vendoo.co. No other extension we have analysed sends data here.
