Top Risks

• Uninstall & install URL hijacks redirect to tabplugins.com marketing pages — classic monetization shell pattern.
• scripting + *://*/* gives full script injection on every site; very broad for a cursor extension.
• No CSP + innerHTML DOM-XSS sink — unsafe DOM manipulation with no mitigation layer.
• Privacy policy admits data collection and third-party sharing without retention disclosure.
• Low install count (176) with HIGH-tier permissions flags tail-attack-surface anomaly.

Evidence

• uninstall_url_hijack crx setUninstallURL → tabplugins.com/cursors/ with UTM params; monetization redirect confirmed.
• install_url_hijack crx onInstalled opens tabplugins.com promo page with UTM; affiliate/monetization pattern.
• broad_host_permissions manifest host_permissions *://*/* + content_scripts *://*/* + scripting = full-site control.
• dom_sink_innerhtml_userctrl crx innerHTML sink in main.4964ab1e.js; no CSP present → elevated XSS risk.
• privacy_policy_third_party_sharing store Policy admits data collection + third-party sharing; retention not disclosed.
• install_perm_anomaly api 176 installs + HIGH-tier permissions (scripting + all_urls) = small-install high-perm anomaly.
• no_csp crx content_security_policy is null; MV3 default applies but no explicit hardening.
• unverified_developer store No verified publisher badge, no featured badge; WallExt / tabplugins.com unverified.

Permissions Breakdown

• storage low Stores cursor preferences locally; low risk alone.
• unlimitedStorage low Extends storage quota; low risk for cursor asset caching.
• scripting high Allows programmatic script injection into any page; significant capability.
• *://*/* high Broad host access across all sites; pairs with scripting for full page control.
• content_scripts *://*/* high Content scripts run on every page visited; full DOM access on all sites.
