Top Risks

• cookies + WhatsApp host access enables WhatsApp session hijacking and message exfiltration.
• Privacy policy is Google's generic policy — not scoped to this extension; data handling undisclosed.
• No CSP + function_constructor + 3× innerHTML DOM-XSS sinks across app.js, background.js, contentScript.js.
• Gmail dev email, no developer name, no verified publisher — unverifiable identity with sensitive WA access.
• Small install count (18) with high-tier permissions is a tail-attack-surface signal.
