Top Risks

• NewTab override replaces every new tab — high-reach monetization surface with search permission.
• Uninstall and install URL hijacks redirect to developer site with UTM tracking.
• No CSP (csp_present=false) on MV3 extension; two innerHTML DOM-XSS sinks present.
• Developer name missing; verified publisher but no display name reduces accountability.
• Maintenance at 12-month boundary; 910 installs with zero ratings reduces trust signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces new tab for all users.
• uninstall_url_hijack crx setUninstallURL → 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 Two innerHTML sinks in popup.js and calendar.js with no CSP guard — DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit restriction.
• verified_publisher store verified_publisher=true; developer domain resolves, not throwaway, scoped privacy policy.
• search_permission_newtab_combo manifest search permission + newtab override is classic ad-monetization pattern for wallpaper shells.
• maintenance_12mo store months_since_update=12; on 6-12mo boundary → +3.5 maintenance score.

Permissions Breakdown

• search medium Allows reading/manipulating search queries; paired with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-reach surface for every new tab opened.
