Is Lightning Autofill safe?

Medium risk

Lightning Autofill fetches encrypted JavaScript from its servers and injects it into every web page for paid license holders.

For users with a paid license (tier 2 or above), the extension periodically contacts api.lightningautofill.com, downloads AES-GCM-encrypted code blobs, decrypts them using the user's license key as key material, and registers the resulting scripts into the MAIN world on all web pages at document_start. The injected scripts run with eval enabled (unsafe-eval CSP) and can read and modify any page the user visits.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 5 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.
