Top Risks

• jQuery 1.9.1 bundles 3 medium CVEs (XSS); fixed versions available since 2019–2020; library not updated.
• dom_sink_innerhtml_userctrl in readability.js combined with CVEs elevates DOM-XSS risk on all visited pages.
• Free-webmail developer (gmail) with no developer name listed; privacy policy not scoped to this extension.
• install_url_hijack and uninstall_url_hijack flags set; onInstalled opens third-party URL.
• Privacy policy admits data collection but not scoped to extension; no retention period disclosed.

Evidence

• jquery_cve_bundle crx jquery@1.9.1 bundles CVE-2019-11358, CVE-2020-11023, CVE-2015-9251 (all medium XSS); fixed in 3.5.0.

• free_webmail_dev_no_name store Developer email ryzalyusoff@gmail.com; developer_name empty; verified_publisher=true mitigates partially.
• privacy_policy_not_scoped api Policy fetched; scope_extension=false, data_collection=true, third_party_sharing=false, retention=false.
• dom_sink_plus_cve crx dom_sink_innerhtml_userctrl in readability.js + active jQuery CVEs elevate DOM-XSS risk.
• function_constructor crx new Function() in pdf.js and pdf.worker.js — PDF.js feature-detect pattern, lower exploitation risk.
• broad_host_access manifest <all_urls> host_permissions + content_scripts on all URLs; justified for ReaderMode category.
