Top Risks

• Uninstall and install URL hijack both active — redirects users to gameograf.com on install/uninstall.
• NewTab override replaces every new tab; primary monetization/data surface.
• Two innerHTML DOM-XSS sinks with no CSP; potential XSS if API response is attacker-controlled.
• No developer name listed; verified publisher badge but empty 'Offered by' field.
• search permission combined with NewTab override allows query interception.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL to gameograf.com with UTM tracking params.
• install_url_hijack manifest onInstalled opens gameograf.com with UTM tracking params.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new tab.
• dom_xss_sink crx innerHTML assignments in popup.js and calendar.js with no CSP guard; DOM-XSS risk.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store verified_publisher=true for support@gameograf.com; developer_name field is empty.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• low_installs store Only 71 installs; very low reach limits blast radius.

Permissions Breakdown

• search medium Allows reading and manipulating search queries; medium risk for a NewTab theme.
• host_permission: https://api.gameograf.com/* low Scoped to own API domain only; low risk.
• chrome_url_overrides.newtab medium Replaces new tab page; core monetization/data-collection surface for NewTab shells.
