Top Risks

• NewTab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• Uninstall and install URL hijacked to third-party with UTM tracking parameters.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP — elevated XSS risk.
• No developer name listed; verified publisher but low-install wallpaper extension with newtab+search override.
• External JS host list includes chat.openai.com and multiple Google services beyond stated wallpaper function.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — controls every new tab for 234 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
• dom_xss_sink crx innerHTML from variable in js/popup.js and js/calendar.js with no CSP — DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• external_hosts_broad crx JS references chat.openai.com and 10 other external domains beyond api.gameograf.com.
• search_permission manifest 'search' permission declared on a wallpaper/newtab extension — can intercept queries.
• verified_publisher_no_developer_name store Verified publisher badge present but developer_name is empty string.

Permissions Breakdown

• search medium Can read/intercept search queries; notable for a wallpaper/newtab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain; used for wallpaper/config data retrieval.
• chrome_url_overrides.newtab medium Replaces new-tab page; high reach, every new tab is controlled by extension.
