Top Risks

• NewTab override with search permission: classic traffic-monetization surface despite low current install count.
• Uninstall and install URL hijack both active — redirects users to gameograf.com on install/uninstall.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP amplifying risk.
• No developer name listed; verified publisher discount partially offset by missing dev name.
• External JS hosts include OpenAI and multiple Google services beyond what a wallpaper extension requires.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — high-reach replacement of every new tab.
• 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=lofi&utm_medium=install
• dom_xss_sinks crx innerHTML user-controlled in popup.js and calendar.js; no CSP present (MV3, csp_present=false).
• external_hosts_scope_mismatch crx JS contacts chat.openai.com among 12 hosts — unexpected for a wallpaper/NewTab extension.
• verified_publisher store support@gameograf.com verified; domain resolves, not throwaway; no CVEs, not stale.
• privacy_policy api Policy fetched, scoped to extension, discloses collection/retention/3rd-party sharing. Adequate.
• no_developer_name store developer_name is empty string in listing despite verified_publisher status.

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-reach surface for traffic monetization.
