Findings

  • medium Content-Security-Policy does not restrict scripts
    The Content-Security-Policy has no script-src or default-src, so it does not limit which scripts can run.
  • medium Hard-coded JWT in front-end code
    A static JSON Web Token is embedded in the site JavaScript and may grant API access to anyone.
  • 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.
  • 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 2 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.
