Top Risks

• NewTab override with install/uninstall URL hijack — classic monetization shell pattern.
• Uninstall URL hijack to gameograf.com with UTM tracking parameters.
• Install URL hijack fires on extension install to 3rd-party landing page.
• DOM-XSS sink (innerHTML) in popup.js with no CSP present on MV3.
• No developer name listed despite verified publisher status.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new-tab page for all users.
• 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_sink_innerhtml_userctrl crx js/popup.js assigns innerHTML from variable with no CSP guard — DOM-XSS risk.
• no_csp manifest content_security_policy is null on MV3; no CSP protection for inline sinks.
• verified_publisher store verified_publisher=true, domain resolves, privacy policy scoped and complete.
• privacy_policy_classification api Policy fetched, scoped to extension, discloses data collection, retention, and 3rd-party sharing.
• maintenance_stale store 12 months since last update; falls in 6-12mo band (+3.5).

Permissions Breakdown

• search medium Search API access; used by NewTab extensions to redirect/override search queries.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain only; low surface area.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization and tracking entry point.
