Findings

  • low CSP allows 'unsafe-inline' scripts
    The Content-Security-Policy allows inline scripts ('unsafe-inline'), which removes most of its protection against XSS.
  • low DNSSEC not enabled
    DNS answers for the domain are not signed, so a resolver-level attacker could redirect users to a fake front end.
  • low No Referrer-Policy
    Full page URLs (which can carry addresses or tokens) may be sent to third-party sites in the Referer header.
  • low Third-party scripts without Subresource Integrity
    Scripts are loaded from third-party hosts without integrity hashes, so a compromised CDN or package can inject code.
  • info No Permissions-Policy
    The site does not restrict powerful browser features (camera, microphone, payment, USB) for itself and embedded frames.
  • info Third-party scripts
    The homepage loads scripts from 4 third-party origin(s); each one can read and change the wallet UI.

Evidence, exact locations and fixes are in the deep report. How scoring works.
