CVE-2026-50010— netty 加密问题漏洞

Netty's wrapping plain trust manager silently disables hostname verification

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, SimpleTrustManagerFactory.engineGetTrustManagers() and related paths wrap any user-supplied plain X509TrustManager in X509TrustManagerWrapper, which extends X509ExtendedTrustManager but implements the 3-arg checkServerTrusted(chain, authType, SSLEngine) by discarding the SSLEngine and calling the 2-arg delegate. Because the object now IS an X509ExtendedTrustManager, neither SunJSSE's internal AbstractTrustManagerWrapper nor Netty's own OpenSslX509TrustManagerWrapper will re-wrap it to add endpoint-identification. Consequently, even though Netty 4.2 sets endpointIdentificationAlgorithm="HTTPS" by default, a client built with `SslContextBuilder.forClient().trustManager(somePlainX509TrustManager)` performs no hostname verification at all. Versions 4.1.135.Final and 4.2.15.Final patch the issue.

netty 加密问题漏洞

Netty是Netty团队开源的一款非阻塞I/O客户端-服务器框架, 它主要用于开发Java网络应用程序,如协议服务器和客户端等。 Netty 4.1.135.Final之前版本和4.2.15.Final之前版本存在加密问题漏洞，该漏洞源于SimpleTrustManagerFactory.engineGetTrustManagers()相关路径将用户提供的纯X509TrustManager包裹在X509TrustManagerWrapper中，但X509ExtendedTrustManager包装后未能
