In Apache CXF, the Netty-based HTTP client transport (cxf-rt-transports-http-netty-client) did not verify that the hostname in the server\u2019s TLS certificate matched the host being called. This applied over both HTTP\/1.1 and HTTP\/2, even when disableCNCheck was left at its default value of false. The certificate chain was validated against the configured trust store, but the endpoint\u2019s identity was not. A network attacker able to intercept traffic could present any certificate trusted by the client, such as a publicly issued certificate for a domain they control, and impersonate the target service. They could then read or modify the exchanged messages, including credentials.\u00a0
