Top Risks

• NewTab override with uninstall/install URL hijack to gameograf.com — classic monetization shell pattern.
• Uninstall and install URL hijacks both redirect to 3rd-party domain with UTM tracking.
• Two innerHTML DOM-XSS sinks with no CSP — elevation of code quality risk.
• No developer name listed; 'Offered by' field blank reduces accountability.
• Very low install count (8) with NewTab override is a tail-attack-surface concern.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party UTM).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party UTM).
• dom_xss_sink crx innerHTML sinks in popup.js and calendar.js with no CSP — DOM-XSS risk elevated (FIX B applies).
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• no_developer_name store developer_name is empty string — reduced accountability signal.
• verified_publisher store Extension carries verified publisher badge for gameograf.com domain.
• search_permission_newtab manifest search permission + newtab override + single search engine (google.com) — monetization shape.

Permissions Breakdown

• search medium Allows reading/modifying search queries; combined with NewTab override, enables search monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for monetization and data collection.
