Top Risks

• Uninstall and install URL hijack to gameograf.com — classic NewTab monetization shell pattern.
• NewTab override replaces every new-tab page for all users; high-reach surface.
• Two innerHTML DOM-XSS sinks with no CSP — elevates injection risk if API data is attacker-influenced.
• No developer name listed despite verified publisher status; accountability gap.
• Low install count (94) with full NewTab override and search permission — low blast radius today but pattern matches monetization shell.

Evidence

• uninstall_url_hijack crx chrome.runtime.setUninstallURL points to gameograf.com UTM-tracked URL — monetization shell signal.
• install_url_hijack crx onInstalled opens gameograf.com UTM-tracked URL — install URL hijack confirmed.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new tab replaced by extension.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• dom_xss_sinks crx innerHTML used in popup.js and calendar.js without sanitization; no CSP to mitigate.
• verified_publisher store Verified publisher badge present for gameograf.com; domain resolves, not throwaway.
• privacy_policy_scope api Policy scoped to extension, discloses collection, retention, and third-party sharing — adequate.
• no_developer_name store developer_name is empty string despite verified_publisher == true; accountability gap.

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; consistent with stated function.
• chrome_url_overrides.newtab medium Replaces new tab page — primary monetization surface for this category.
