Top Risks

  • Privacy policy admits data collection and third-party sharing but is not scoped to this extension — scores max privacy risk.
  • Developer uses free Gmail address with no verified business identity and no developer name listed.
  • Content script injected on <all_urls> gives broad page-content access across every site visited.
  • new Function() constructor found in all 4 JS files; MV3 with no CSP leaves dynamic code execution unmitigated.
  • AI extension processes page content and sends it externally; combined with vague privacy policy, data exfil risk is elevated.

Evidence

  • gmail_developer_no_name store Developer email is kalresanikysa@gmail.com; developer_name is empty — free webmail, no business identity.
  • privacy_policy_scope_mismatch api Policy fetched but scope_extension=false, data_collection=true, third_party_sharing=true — generic policy admitting data share.
  • host_permissions_all_urls manifest <all_urls> host permission + content_scripts on <all_urls>; AI extension reads every page.
  • function_constructor_all_files crx new Function() constructor present in all 4 JS files (background, chat, content-sidebar, options).
  • no_csp manifest content_security_policy is null; no CSP declared on MV3 extension with dynamic code patterns.
  • js_external_host_github crx js_external_hosts includes github.com — external JS dependency outside developer control.
  • verified_publisher_featured store verified_publisher=true and is_featured_by_google=true; discounts applied but capped due to privacy issues.
  • ai_page_content_processing store AI extension category with <all_urls> content scripts; page content likely sent to external AI API.

Permissions Breakdown

  • storage low Stores user preferences/config locally; minimal risk.
  • tabs medium Can read tab URLs and titles; moderate info exposure.
  • <all_urls> (host_permission) high Content script injected on every site; broad read/write access to all page content.
