Top Risks

• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and 3rd-party sharing.
• NewTab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• No CSP present; two unguarded innerHTML DOM-XSS sinks in popup.js and calendar.js.
• Developer name absent; verified publisher but generic Google privacy URL not scoped to extension.
• Uninstall and install URL hijack both redirect to developer marketing pages with UTM tracking.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page entirely.
• uninstall_url_hijack crx setUninstallURL → 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
• generic_privacy_policy api Privacy URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP declared.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js with no CSP guard.
• developer_name_missing store developer_name field is empty string; no 'Offered by' identity visible.
• verified_publisher store verified_publisher=true for gameograf.com domain which resolves and is not throwaway.

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with newtab override raises risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; high user-facing impact, monetization vector.
