CVE-2026-59272Network attack vectorHinoki check available

Log interception via disabled TLS hostname verification

Published Aug 27, 2026 · Updated Aug 28, 2026

Improper certificate validation in Spring AMQP affected releases allows man-in-the-middle attackers to read or alter AMQP log traffic. The Log4j2 AmqpAppender leaves RabbitMQ TLS hostname verification disabled when its documented default is used, accepting a certificate for the wrong host without an error. Exposure requires TLS log shipping through the appender with the default setting and an attacker on the network path; intercepted events can disclose secrets or be modified in transit.
