Top Risks

• NewTab override replaces every new-tab page — high-reach monetization surface with search override capability.
• Uninstall and install URL hijacking redirect users to developer site with UTM tracking.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP to mitigate.
• No CSP on MV3 extension with DOM sinks; v2 +2.0 MV2/no-CSP rule not triggered but DOM risk is amplified.
• Developer name field empty; no 'Offered by' display name despite verified publisher status.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab for all users.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM params — traffic-monetization pattern.
• install_url_hijack crx onInstalled opens gameograf.com with UTM params — install-time redirect.
• dom_xss_sink crx innerHTML sinks in popup.js and calendar.js; no CSP to block exploitation.
• verified_publisher store gameograf.com verified publisher; domain 2051 days old, 265 certs — established.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, and 3rd-party sharing.
• no_csp manifest content_security_policy is null; MV3 has default CSP but DOM sinks remain unmitigated.
• no_cve crx jquery 3.7.1 bundled — no CVEs found; cve_findings_raw empty.

Permissions Breakdown

• search medium Allows reading/modifying search queries; relevant to NewTab/search-provider pattern.
• host_permission: https://api.gameograf.com/* low Scoped to own API domain only; not broad host access.
• chrome_url_overrides.newtab medium Replaces new-tab page — high-reach surface, monetization vector.
