Top Risks

• NewTab override captures every new tab; install+uninstall URL hijack to gameograf.com signals monetization shell.
• Uninstall and install URL hijack both redirect to gameograf.com — traffic-monetization pattern.
• Two innerHTML DOM-XSS sinks in popup.js and calendar.js with no CSP to mitigate.
• No developer name listed despite verified publisher status; reduces accountability.
• MV3 but no CSP declared; innerHTML sinks are unmitigated by browser policy.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL points to https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js; no CSP present to block exploitation.
• no_csp manifest content_security_policy is null; DOM-XSS sinks are unmitigated.
• verified_publisher store gameograf.com resolves, not throwaway; verified publisher status confirmed.
• privacy_policy_scoped api Policy fetched, scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name field is empty string despite verified publisher badge.

Permissions Breakdown

• search medium Allows reading/manipulating search queries; expected for NewTab extensions.
• host: https://api.gameograf.com/* low Scoped to own API domain only; low blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab — high-reach surface for monetization or data capture.
