Top Risks

• NewTab override replaces every new-tab page; persistent monetization surface with uninstall/install URL hijacks.
• Uninstall and install URL hijacks redirect to gameograf.com with tracking parameters.
• Two innerHTML DOM-XSS sinks with no CSP present, elevating XSS exploitability.
• No developer name listed despite verified publisher status; reduced accountability.
• Extension updated 12 months ago; approaching stale threshold.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL redirects to gameograf.com with UTM tracking on uninstall.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking on first install.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• dom_xss_sink crx Two innerHTML assignments from variables in popup.js and calendar.js without CSP.
• verified_publisher store Verified publisher badge present; developer domain resolves and is not throwaway.
• privacy_policy_adequate api Policy scoped to extension, discloses data collection, retention, and third-party sharing.
• no_developer_name store developer_name is empty string despite verified publisher status.

Permissions Breakdown

• search medium Allows reading/modifying search queries; standard for NewTab but increases data exposure.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low blast radius.
• chrome_url_overrides: newtab medium Replaces new-tab page; monetization surface and persistent reach.
