Top Risks

• NewTab override replaces every new tab page — high-reach monetization/tracking surface.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking on both events.
• No CSP declared (MV3); dom_sink_innerhtml_userctrl in popup.js and calendar.js raises DOM-XSS risk.
• Developer name absent; only email identity; verified publisher badge partially offsets but dev name missing.
• search permission paired with newtab override enables full search-provider takeover pattern.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html — 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; csp_present=false on MV3 extension with innerHTML sinks.
• dom_xss_sink crx innerHTML used with variable input in js/popup.js and js/calendar.js — DOM-XSS risk.
• verified_publisher store Verified publisher badge present for gameograf.com; domain resolves; not throwaway.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• search_permission_newtab_combo manifest search permission + newtab override combined enables search-provider takeover pattern.

Permissions Breakdown

• search medium Search API allows overriding search provider; medium risk on its own.
• chrome_url_overrides.newtab high Replaces every new tab — high reach, traffic monetization surface, scored as MEDIUM+override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
