Is Zotero Connector safe?

Clean risk

Zotero Connector ships a hardcoded OAuth 1.0a consumer secret in its extension bundle.

The extension includes a fixed client secret in zotero_config.js that is used to sign OAuth request-token and access-token exchanges with www.zotero.org. Anyone who extracts this value from the published extension can craft valid signed OAuth requests that Zotero's server treats as coming from the official Connector application.

Shared hosts - 8 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 Zotero Connector 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.

  • www.zotero.org

    Zotero Connector sends data to www.zotero.org. No other extension we have analysed sends data here.
