Top Risks

• NewTab override with uninstall URL hijack and install URL hijack — monetization shell pattern.
• Two innerHTML DOM-XSS sinks with no CSP on MV3 extension.
• No developer name listed; verified publisher but anonymous display.
• Search permission paired with NewTab override enables query interception.
• Low install count (306) limits blast radius but pattern matches low-effort traffic-monetization.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab.
• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install tracking params.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store Developer verified via Chrome Web Store; domain resolves, not throwaway.
• privacy_policy_adequate api Policy fetched, scoped to extension, discloses data collection, retention, and third-party sharing.
• no_bad_hosts_no_cves api No bad host hits, no CVEs, no monetization/affiliate hits, no review red flags.

Permissions Breakdown

• search medium Allows reading/manipulating search queries; relevant to NewTab monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for NewTab monetization/redirect.
