Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Infinite Mario Bros Offline + malext.io malicious_extension_sentry (+2.5, capped).
• jquery@1.4.2 bundles 6 moderate CVEs (XSS); no CSP amplifies exploit risk via jquery<3.5+no-CSP rule
• Privacy policy on unblockedgames6x.org admits data collection and 3rd-party sharing without extension-specific scope (+10.0)
• Uninstall URL hijack detected — extension registers uninstall callback to external destination
• Install URL hijack opens infinite.html on install — low-grade onInstalled redirect pattern
