Top Risks

• NewTab override replaces new-tab page with install/uninstall URL hijacking — classic monetization shell pattern.
• Uninstall and install URL hijacks redirect to developer domain with UTM tracking parameters.
• Two innerHTML DOM-XSS sinks with no CSP present, elevating DOM injection risk.
• No developer name listed despite verified publisher status; 'Pokemon' in title may attract brand scrutiny.
• No CSP defined (MV3 default applies but no explicit content_security_policy) combined with innerHTML sinks.

Evidence

• uninstall_url_hijack manifest setUninstallURL points to gameograf.com with UTM params — monetization tracking on uninstall.
• install_url_hijack manifest onInstalled opens gameograf.com with UTM params — install-event redirect to 3rd-party URL.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new-tab page.
• dom_sink_innerhtml_userctrl crx innerHTML sinks in popup.js and calendar.js with no CSP; DOM-XSS risk.
• verified_publisher store Developer is verified publisher at gameograf.com which resolves and is not throwaway.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string despite verified publisher status.
• low_install_newtab store Only 607 installs for a NewTab extension with install/uninstall URL hijacks — limited blast radius now.

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk in NewTab context.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides: newtab medium Replaces new-tab page — primary monetization/search-redirect surface.
