Top Risks

• NewTab override replaces every new tab page, intercepting navigation for all users.
• Uninstall URL hijack sends users to developer marketing page on removal.
• Install URL hijack redirects users to third-party page on install.
• DOM-XSS sink (innerHTML) in calendar.js with no CSP to mitigate exploitation.
• No developer name listed; publisher accountability is weak despite verified_publisher flag.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?p=33124?utm_source=extension&utm_medium=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=33124?utm_source=extension&utm_medium=install
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js; no CSP to block exploitation.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store verified_publisher=true with resolving domain gameograf.com; partial trust signal.
• no_developer_name store developer_name is empty string; reduces accountability.
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true.

Permissions Breakdown

• search medium Can read and manipulate search queries; elevated for a wallpaper/NewTab extension.
• alarms low Scheduling only; minimal risk.
• storage low Local settings persistence; low risk.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization surface, intercepts user navigation intent.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; single-origin, low blast radius.
