CVE-2025-68161 is a vulnerability in Apache Log4j Core affecting the Socket Appender in versions 2.0-beta9 through 2.25.2. The appender fails to perform TLS hostname verification on the peer certificate even when hostname verification is explicitly enabled through the verifyHostName configuration attribute or the log4j2.sslVerifyHostName system property. As a result, the TLS peer identity is not properly validated against the intended server name, defeating an expected protection against certificate-based impersonation. The flaw affects deployments that send log events over TLS using the Socket Appender and can expose log transport to interception or redirection by an active network adversary under specific trust conditions.
