CVE-2026-107938— Apache CXF: The Netty HTTP client transport does not perform TLS hostname verification.

Quick assessment

Affected
Apache Software Foundation Apache CXF
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Apache CXF 中，基于 Netty 的 HTTP 客户端传输组件（cxf-rt-transports-http-netty-client）未验证服务器 TLS 证书中的主机名是否与正在调用的目标主机相匹配。该问题在 HTTP/1.1 和 HTTP/2 协议下均存在，即使将 disableCNCheck 参数保持在其默认值 false 也不例外。虽然证书链会按照配置的信任库进行验证，但服务端的身份并未得到验证。攻击者若能拦截网络流量，即可出示客户端信任的任何证书（例如，由公共证书颁发机构签发的、属于攻击者

Vulnerability Title
Apache CXF: The Netty HTTP client transport does not perform TLS hostname verification.
Source: CVE Program / CVE List V5
Vulnerability Description
In Apache CXF, the Netty-based HTTP client transport (cxf-rt-transports-http-netty-client) did not verify that the hostname in the server’s 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’s 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.  Users are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.
