Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Palant affiliate fraud cluster (name unconfirmed) [adware] (+2.0, capped).
• Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• Content scripts declared against <all_urls> giving broad page-level JS access despite stated Google Docs focus.
• Extension loads JS from external host google-edit.com (non-Google domain) — potential supply-chain risk.
• Developer uses free-webmail (gmail) with no verified publisher badge; identity unverifiable.

Evidence

• content_scripts_matches <all_urls> manifest content_scripts match includes <all_urls> — far broader than stated Google Docs function.
• external JS host: google-edit.com crx JS loaded from google-edit.com — not owned by Google; look-alike domain is high supply-chain risk.

• free-webmail developer, no verified publisher store Developer konimatoan@gmail.com; verified_publisher=false; identity unverifiable.
• dom_sink_innerhtml_userctrl crx innerHTML from variable in contentScript.js and popup.js — DOM-XSS sinks; CSP present mitigates somewhat.
