Top Risks

• NewTab override with uninstall/install URL hijack to gameograf.com — monetization shell pattern.
• No CSP on MV3 extension with innerHTML sinks in popup.js and calendar.js — DOM-XSS risk.
• Missing developer name on store listing reduces accountability.
• innerHTML sinks without CSP: +2.0 code quality amplifier applies (FIX B).
• Privacy policy scoped and adequate; core risk is newtab monetization + URL hijack signals.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page.
• 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 dom_sink_innerhtml_userctrl in js/popup.js and js/calendar.js without CSP.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway.
• missing_developer_name store developer_name is empty string; reduces attribution/accountability.
• privacy_policy_adequate api Policy fetched, scoped to extension, data_collection+retention+third_party_sharing all disclosed.

Permissions Breakdown

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