Top Risks

• NewTab override enables search-query interception and monetization for all new-tab searches.
• Uninstall and install URL hijacks redirect to gameograf.com — traffic monetization pattern.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP to mitigate exploitation.
• No developer name listed; verified publisher discount applies but accountability still limited.
• Privacy policy admits third-party data sharing; extension collects data via new-tab position.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab page for all users.
• uninstall_url_hijack crx chrome.runtime.setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install.
• dom_xss_sinks crx Two innerHTML assignments from variables in popup.js and calendar.js; no CSP to block exploitation.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• verified_publisher store Verified publisher badge present for gameograf.com; domain resolves and is not throwaway.
• privacy_policy_third_party_sharing api Policy scoped to extension, data collection and third-party sharing both true; retention disclosed.
• low_installs store Only 98 installs; minimal blast radius currently but pattern matches wallpaper-shell monetization.

Permissions Breakdown

• search medium Allows reading/manipulating search queries; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search monetization.
