Top Risks

• NewTab override combined with install/uninstall URL hijacking — monetization shell pattern.
• Extension stale 15 months; no updates since June 2025 baseline check.
• DOM-XSS sink (innerHTML on user-controlled variable) in popup.js with no CSP.
• No developer name listed; verified publisher discount limited.
• Uninstall URL hijack redirects to gameograf.com — tracking on exit.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg&utm_content=install
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit policy set.
• dom_xss_sink crx js/popup.js: innerHTML assigned from variable without sanitization — DOM-XSS risk.
• verified_publisher store Publisher verified; -3.0 base discount applied but capped at -1.0 due to 15mo staleness.
• privacy_policy_adequate api Policy scoped to extension, discloses data collection, retention, and third-party sharing.
• months_since_update store 15 months since last update — maintenance pillar +6.0 (12-24mo band).

Permissions Breakdown

• search medium Allows reading/overriding search provider; medium risk in isolation.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium NewTab override replaces browser new-tab page; monetization surface.
