Spring AMQP connections may skip certificate checks

CVE-2026-41714 · published 4 months ago
Summary

If a Spring AMQP app sets the broker URL with amqps:// but does not also enable SSL explicitly, the connection will encrypt data but will not verify the server’s certificate or hostname. This makes it possible for an attacker to intercept or impersonate the broker. Upgrade to a version where the issue is fixed or ensure setUseSSL(true) is called when configuring the connection.

What to do
  • Update springframework org.springframework.amqp:spring-amqp to version 4.0.4.
  • Update springframework org.springframework.amqp:spring-amqp to version 3.2.11.

Original advisory text
In Spring AMQP the RabbitConnectionFactoryBean.setUri("amqps://...") bypasses secure SSL setup, uses TrustEverythingTrustManager
Applications that configure their broker connection via RabbitConnectionFactoryBean.setUri("amqps://...") without also calling setUseSSL(true) get TLS encryption with no certificate validation and no hostname verification.

Affected versions:
Spring AMQP 4.0.0 through 4.0.3; 3.2.0 through 3.2.10; 3.1.0 through 3.1.15; 2.4.0 through 2.4.17.
