Top Risks

  • jquery@3.3.1 bundles 3 moderate XSS CVEs (CVE-2019-11358, CVE-2020-11022, CVE-2020-11023); no CSP amplifies risk.
  • Developer uses free-webmail email (gmail) with no developer name listed.
  • last_updated missing — maintenance posture unknown; stale library version reinforces concern.
  • description_promise flags is_shell_pattern=true; extension appears to be a game wrapper.
  • Privacy policy third_party_silence=true; no explicit statement on third-party data sharing.

Evidence

  • cve_moderate_x3_jquery crx jquery@3.3.1 has 3 moderate CVEs (XSS); fixed_in 3.5.0. No CSP present on MV3 extension.
  • no_csp_present manifest content_security_policy is null; no CSP defined, raising DOM-XSS exposure from CVE-laden jQuery.
  • dom_sink_innerhtml_userctrl crx Clock.js assigns timer variables to innerHTML — DOM-XSS sink, elevated by missing CSP + CVEs.
  • free_webmail_no_devname store developer_email=deben3@gmail.com; developer_name is empty. Reputation penalty applies.
  • verified_publisher_featured store verified_publisher=true AND is_featured_by_google=true; reputation discounts applied.
  • shell_pattern_game store description_promise.is_shell_pattern=true; game wrapper extension with 1M installs.
  • maintenance_unknown store last_updated and months_since_update are null; stale library version suggests possible abandonment.
  • privacy_third_party_silence api Privacy policy fetched, scoped, retention present, but third_party_silence=true; +1.0 applied.
