Top Risks

• NewTab override replaces every new tab — persistent high-reach monetization surface with search permission.
• Uninstall URL hijack redirects to gameograf.com marketing page on removal.
• Install URL hijack opens third-party tracking URL on installation.
• DOM-XSS sinks (innerHTML) in popup.js and calendar.js with no CSP on MV3.
• No developer name listed; low install count (106) limits blast radius but reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• 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=lofi&utm_medium=install.
• dom_xss_sinks crx innerHTML assigned from variables in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• verified_publisher store Verified publisher badge present; domain gameograf.com resolves and is not throwaway.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_installs store Only 106 installs limits blast radius; no ratings, no review red flags detected.

Permissions Breakdown

• search medium Allows reading/modifying search queries; concerning in NewTab context with search override capability.
• chrome_url_overrides.newtab high Replaces new tab page — high-reach, persistent monetization surface for every new tab opened.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low breadth but enables data transmission.
