Echo: io.netty:netty-handler: security update to 4.1.135.Final

high Tenable Self-Hosted Container Security Plugin ID 460929

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-50010)

Solution

Update the io.netty:netty-handler library and its related packages to version 4.1.135.Final or later.
