Findings

  • medium No HTTP Strict Transport Security
    Browsers are not told to always use HTTPS, so a network attacker can downgrade the first visit and swap the front end.
  • low CSP allows 'unsafe-inline' scripts
    The Content-Security-Policy allows inline scripts ('unsafe-inline'), which removes most of its protection against XSS.
  • 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 No security.txt
    There is no /.well-known/security.txt, so researchers who find a vulnerability have no published way to report it.
  • info No CAA record
    Any certificate authority may issue certificates for the domain.
  • 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 1 third-party origin(s); each one can read and change the wallet UI.
