Top Risks

  • proxy + webRequest + *://*/* enables full interception and rerouting of all browser traffic through developer-controlled servers
  • Privacy policy is unscoped (scope_extension=false), collects data, shares with third parties — triggers +10.0 privacy score
  • jquery@1.9.1 bundled with 3 medium CVEs (CVE-2015-9251, CVE-2019-11358, CVE-2020-11023); no CSP to mitigate DOM-XSS sinks
  • Install and uninstall URL hijacks present; rating 2.4 indicates poor user experience or suspected abuse
  • 12 external JS hosts including suspicious domains (91.notredamme.com, flag-gimn.ru, staging-server.worksqr.com) with no CSP

Evidence

  • proxy+webRequest+all_urls manifest proxy, webRequest, webRequestAuthProvider paired with *://*/* — complete traffic interception capability for a VPN.
  • privacy_policy_unscoped_with_data_sharing crx Policy fetched; scope_extension=false, data_collection=true, third_party_sharing=true — triggers D clause +10.0.
  • jquery_1.9.1_three_medium_cves crx jquery@1.9.1 carries CVE-2015-9251, CVE-2019-11358, CVE-2020-11023 (all moderate); no CSP present.
  • install_uninstall_url_hijack crx Both install_url_hijack and uninstall_url_hijack are true; targets not captured but pattern is monetization indicator.
  • suspicious_external_hosts crx 12 external JS hosts including 91.notredamme.com, flag-gimn.ru, staging-server.worksqr.com — non-canonical for a VPN.
  • no_csp_mv3 manifest content_security_policy is null; MV3 but no explicit CSP — amplifies CVE XSS risk from bundled jQuery.
  • no_developer_name store developer_name is empty string; reduces accountability, +1.0 reputation.
  • low_rating store Rating 2.4 with 60,000 installs; poor user trust signal.
