Top Risks

• NewTab override replaces every new tab page, enabling persistent search/ad monetization.
• Uninstall and install URL hijacking sends tracking events to developer domain on both events.
• Two innerHTML DOM-XSS sinks without CSP; no content_security_policy declared (MV3 default only).
• search permission paired with newtab override allows query interception for monetization.
• Developer name blank; verified publisher status partially mitigates identity opacity.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_sink crx innerHTML sinks in popup.js and calendar.js; csp_present=false amplifies XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway; partially mitigates reputation risk.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true. Adequate.
• no_developer_name store developer_name is empty string; identity relies solely on email and verified publisher badge.

Permissions Breakdown

• search medium Allows reading and modifying search queries; paired with NewTab override raises monetization concern.
• chrome_url_overrides.newtab medium Replaces every new-tab page; primary surface for NewTab monetization shells.
• host_permissions: https://api.gameograf.com/* low Scoped to developer-owned API domain only; limited blast radius.
