Top Risks

• NewTab override replaces every new-tab page — primary traffic/monetization capture surface.
• Uninstall and install URL hijack to gameograf.com with UTM tracking on every install/uninstall.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP in place (MV3 but csp_present=false).
• No developer name listed; verified publisher but anonymous identity reduces accountability.
• Low install count (222) reduces blast radius but also reduces trust signal for a wallpaper/NewTab extension.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — hijacks every new-tab page 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=extension&utm_medium=install.
• dom_sink_innerhtml_userctrl crx innerHTML sinks in popup.js and calendar.js; no CSP to mitigate DOM-XSS risk.
• no_developer_name store developer_name is empty string; verified publisher but no displayed identity.
• privacy_policy_adequate api Policy fetched, scoped to extension, discloses collection/retention/third-party sharing.
• verified_publisher store Verified publisher badge present; developer domain resolves and is not throwaway.
• cve_findings_empty crx jquery 3.7.1 bundled — no CVEs found. No bad-host or monetization hits in threat_intel.

Permissions Breakdown

• search medium Allows query/modify of search settings; combined with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; limits exfil surface to one controlled endpoint.
• chrome_url_overrides.newtab medium Replaces every new-tab page; primary monetization/traffic capture vector for this category.
