Top Risks

• NewTab override enables search monetization; paired with 'search' permission and uninstall/install URL hijacks.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking — monetization shell pattern.
• Two innerHTML DOM-XSS sinks with no CSP; MV3 but csp_present==false amplifies code quality risk.
• Developer name absent; no 'Offered by' name increases accountability gap for a NewTab extension.
• Extension contacts 12 external JS hosts including chat.openai.com beyond its stated wallpaper function.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party redirect).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install (monetization pattern).
• dom_xss_sinks_no_csp crx 2x innerHTML from variable in popup.js and calendar.js; csp_present==false increases XSS exposure.
• broad_js_external_hosts crx 12 external JS hosts incl. chat.openai.com; far beyond wallpaper stated function.
• no_developer_name store developer_name is empty string; no 'Offered by' identity shown in store listing.
• verified_publisher store verified_publisher==true; partial reputation credit applied, capped due to no developer name.
• privacy_policy_adequate api Policy fetched, scope_extension+data_collection+retention+third_party_sharing all true; adequate.

Permissions Breakdown

• search medium Allows reading and manipulating search queries; medium risk for a NewTab/wallpaper extension.
• host_permissions:https://api.gameograf.com/* low Scoped to developer's own API domain; reasonable for wallpaper content fetch.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface, enables search hijack.
