Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Le Sserafim Wallpapers [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• 9 moderate-severity CVEs in bundled jquery@1.9.1, jquery@3.4.1, jquery-ui@1.12.1 — all versions below fixed thresholds
• NewTab override replaces every new tab; combined with uninstall URL hijack to developer domain
• Extension 18 months stale while carrying multiple unpatched XSS-vulnerable JS libraries
• No CSP defined (MV3 default applies but no explicit policy); no content scripts yet jquery<3.5 combo flagged

Evidence

• newtab_override manifest chrome_url_overrides.newtab = index.html; every new tab is controlled by this extension.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=uninstall — 3rd-party UTM tracking on uninstall.
• cve_medium_multiple crx 9 moderate CVEs across jquery@1.9.1, jquery@3.4.1, jquery-ui@1.12.1 — all below fixed_in versions.
• no_csp manifest content_security_policy is null; csp_present=false. Amplifies XSS risk from vulnerable bundled libs.
• stale_with_cves store 18 months since update; triple-stale fingerprint: >18mo + CVEs + MV3 (stale library risk elevated).
• no_developer_name store developer_name is empty string; identity accountability reduced.
• install_url_hijack crx onInstalled opens index.html (internal); low severity but pattern noted.
• privacy_policy_scope api Privacy policy fetched; scope_extension=true, data_collection=true, retention=true — scoped and adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Le Sserafim Wallpapers [adware] + malext.io malicious_extension_sentry; score 4.51 -> 7.01 (+2.5 cap 2.5).
