Top Risks

  • Uninstall URL hijack to tabplugins.com — classic low-effort traffic-monetization shell pattern (+3.0 webstore).
  • Install URL hijack to tabplugins.com — onInstalled opens 3rd-party URL (+2.0 webstore).
  • Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — worse than no policy (+10.0 privacy).
  • Free-webmail dev (gmail) with no developer name and no business website — unverifiable identity (+reputation floor).
  • scripting + *://*/* allows script injection into every site user visits; no CSP present.

Evidence

  • uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://tabplugins.com/cursors/ — 3rd-party monetization redirect.
  • install_url_hijack manifest onInstalled opens https://tabplugins.com/fnaf-cursor-custom-horror-cursor-for-chrome/ — 3rd-party.
  • privacy_policy_generic store Policy is Google's account policy: scope_extension=false, data_collection=true, third_party_sharing=true.
  • free_webmail_no_dev_name store Dev email mbilalshah0001@gmail.com; developer_name empty; no business domain.
  • broad_host_with_scripting manifest scripting + *://*/* on MV3 without CSP; can inject into any page.
  • dom_sink_innerhtml_userctrl crx innerHTML assignment from variable in main.4964ab1e.js — DOM-XSS sink.
  • no_csp manifest content_security_policy is null; MV3 default applies but no explicit restriction.
  • verified_publisher_cap store verified_publisher=true but free-webmail dev, no domain; discount capped per 0c (monetization shell signals).

Permissions Breakdown

  • storage low Stores cursor preferences locally; low standalone risk.
  • unlimitedStorage low Extends storage quota; minimal risk for a cursor extension.
  • scripting high Paired with *://*/* host access: can inject scripts into any page.
  • *://*/* high Broad host access covering all URLs; amplifies scripting risk.
