Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — WA Business [data-theft] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension; admits data collection and third-party sharing.
• cookies permission + access to web.whatsapp.com allows exfiltration of WhatsApp session tokens to developer backend.
• No CSP declared (MV3) combined with innerHTML sinks in content script and background — DOM-XSS exposure.
• Free-webmail developer (gmail.com) with no verified identity; small install base (38) with high-impact permissions.

Evidence

• privacy_policy_generic_google store Privacy policy URL is Google account policy — scope_extension=false, admits data_collection=true and third_party_sharing=true.
• free_webmail_developer store Developer email coderlicences@gmail.com — free webmail, no verified business domain.
• cookies_on_whatsapp manifest cookies permission scoped to web.whatsapp.com allows reading session cookies and auth tokens.
• no_csp crx content_security_policy is null; combined with innerHTML sinks in 3 files creates XSS attack surface.
• function_constructor crx new Function() in app.js; dangerous without CSP to restrict code execution.
• dom_xss_sinks crx dom_sink_innerhtml_userctrl in app.js, background.js, contentScript.js — 3 separate DOM-XSS sinks.
• small_install_high_perm api Only 38 installs but has high-tier permissions (cookies, tabs, declarativeNetRequest) — tail-attack anomaly.
• external_js_hosts crx References notiflix.github.io and reactjs.org as external JS hosts — third-party dependency surface.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — WA Business [data-theft] + malext.io malicious_extension_sentry; score 5.25 -> 7.75 (+2.5 cap 2.5).

Permissions Breakdown

• storage low Standard local data persistence; low risk on its own.
• unlimitedStorage low Allows large local storage; low risk, common for CRM data.
• tabs medium Can read tab URLs/titles; moderate info-disclosure risk.
• cookies high Can read/write cookies scoped to host_permissions (WhatsApp session cookies).
• notifications low Can push desktop notifications; minimal harm potential.
• declarativeNetRequest medium Can block/redirect network requests declaratively; moderate risk.
• https://web.whatsapp.com/* high Full access to WhatsApp Web including messages and session tokens.
• https://app.coderlicences.com/* medium Sends data to developer-controlled backend; unknown data handling.
