Top Risks

• NewTab override replaces every new tab page — high reach monetization/tracking surface.
• Uninstall URL hijack and install URL hijack redirect to gameograf.com tracking URLs.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP to mitigate.
• No developer name listed in store; verified publisher but anonymous identity.
• MV3 + no CSP declared: innerHTML sinks unmitigated by content security policy.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL points to gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com install tracking URL.
• dom_xss_sink crx innerHTML used with variable input in popup.js and calendar.js; no CSP present.
• csp_absent manifest content_security_policy is null — no mitigation for DOM-XSS sinks.
• verified_publisher store Verified publisher badge present; domain resolves; not throwaway.
• privacy_policy api Policy fetched, scoped to extension, covers data collection, retention, third-party sharing.
• no_developer_name store developer_name field is empty in store listing despite verified publisher status.

Permissions Breakdown

• search medium Allows reading/manipulating search queries; elevated in NewTab context.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; no broad host access.
• chrome_url_overrides.newtab medium Replaces every new tab — high reach, monetization surface.
