Top Risks

• NewTab override replaces browser new-tab with wallpaper page — persistent high-reach surface for all users.
• Uninstall and install URL hijacks redirect users to gameograf.com tracking URLs.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP to mitigate exploitation.
• Developer name absent; verified publisher status partially offsets but no named accountability.
• Privacy policy admits data collection and third-party sharing, though scoped and retention stated.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new-tab for all users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP to block exploitation.
• no_csp manifest content_security_policy is null; MV3 default applies but dom_sink findings raise effective risk.
• verified_publisher store verified_publisher=true, domain resolves, not throwaway — partially mitigates reputation risk.
• privacy_policy_classification api Policy fetched, scoped to extension, data_collection+retention+third_party_sharing all true.
• maintenance_window store months_since_update=10 (3-6mo band boundary passed); falls in 6-12mo → +3.5 maintenance score.

Permissions Breakdown

• search medium Allows reading/modifying search queries; meaningful for a NewTab override.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-controlled API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-reach surface, monetization vector.
