Top Risks

• NewTab override replaces every new tab; paired with search permission — classic monetization surface.
• Uninstall and install URL hijacks redirect to gameograf.com tracking URL.
• Two innerHTML DOM-XSS sinks found (popup.js, calendar.js) with no CSP to mitigate.
• No developer name listed; verified publisher discount limited by missing display identity.
• 110 installs with newtab+search override is low-reach but high-capability tail-attack surface.

Evidence

• newtab_override manifest chrome_url_overrides.newtab present — replaces every new tab page for all users.
• uninstall_url_hijack crx setUninstallURL → 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 strict default applies, but no explicit CSP declared).
• dom_xss_sink crx innerHTML user-controlled sinks in popup.js and calendar.js — DOM-XSS risk.
• no_developer_name store developer_name field is empty string; identity accountability reduced.
• verified_publisher store Extension carries verified publisher badge — partial reputation mitigation.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.

Permissions Breakdown

• search medium Can read and manipulate search queries; elevated risk paired with newtab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab — high user reach, monetization surface.
