Kiteworks Secure Data Forms before version 9.5.0 is vulnerable to Server-Side Request Forgery that could allow an unauthenticated, remote attacker to make the server issue arbitrary outbound network requests and read back the responses. This could potentially be used to reach internal-only services or other network-restricted resources.
