Top Risks

• NewTab override combined with 'search' permission enables monetized search injection at scale.
• Uninstall and install URL hijacks track user lifecycle via UTM parameters to gameograf.com.
• Two innerHTML DOM-XSS sinks found (popup.js, calendar.js) with no CSP to mitigate.
• No developer display name on store listing reduces accountability.
• MV3 with no CSP — no strict default mitigates the innerHTML findings.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces browser new-tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=install
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js — DOM-XSS risk with no CSP.
• no_csp manifest content_security_policy is null; csp_present=false. No mitigation for DOM sinks.
• verified_publisher store Developer gameograf.com is a verified publisher; domain resolves and is not throwaway.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• search_permission_newtab manifest 'search' permission paired with newtab override — risk of search monetization on every new tab.

Permissions Breakdown

• search medium Allows querying browser search — elevated for a wallpaper/NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only; expected for content/config fetches.
• chrome_url_overrides.newtab medium Replaces new-tab page — core mechanism for monetization or search injection.
