Top Risks

• NewTab override with uninstall+install URL hijack to gameograf.com — traffic-monetization shell pattern.
• Uninstall and install URL both redirect to 3rd-party marketing URL (+3.0+2.0 Webstore).
• No developer name listed; verified_publisher mitigates but empty dev name is a governance gap.
• Two innerHTML DOM-XSS sinks with no CSP present — potential XSS escalation if API data is attacker-controlled.
• Privacy policy scoped and complete, but policy hosted on same API subdomain as extension backend.

Evidence

• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party monetization).
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; NewTab monetization surface.
• no_csp manifest content_security_policy is null; MV3 strict default applies but no explicit hardening.
• dom_xss_sinks crx 2x dom_sink_innerhtml_userctrl in popup.js and calendar.js with no CSP to mitigate.
• empty_developer_name store developer_name is empty string; verified_publisher flag present but no display name.
• verified_publisher store verified_publisher=true; caps reputation discount, domain resolves, no throwaway signals.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.

Permissions Breakdown

• search medium Allows querying browser search API; relevant to NewTab/search override pattern.
• chrome_url_overrides.newtab medium Replaces new tab page — core monetization surface for this category.
• host_permissions:https://api.gameograf.com/* low Scoped to own API domain; limited blast radius.
