Top Risks

• NewTab override replaces browser new-tab page, persistent monetization/tracking surface on every new tab.
• Uninstall and install URL hijack both redirect to gameograf.com UTM-tagged URL — traffic harvesting pattern.
• No CSP declared (MV3); innerHTML sinks in popup.js and calendar.js present DOM-XSS risk.
• Extension contacts 12 external JS hosts including Google services and gameograf.com API with no CSP guardrail.
• Low install count (51) with newtab+search override is a tail-attack-surface pattern for future abuse.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new tab on every open.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening present.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js — DOM-XSS risk without CSP.
• external_js_hosts crx 12 external hosts referenced in JS including api.gameograf.com, mail.google.com, chat.openai.com.
• low_installs_newtab store Only 51 installs with newtab+search override — small-install high-capability anomaly.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new tab page; monetization vector and persistent user exposure.
