AI-suggested

A fix is available starting from Apache TomEE version 10.0.0-M1. Users should upgrade to this version or later. Until upgrading, users are recommended to block network access to Hessian endpoints from untrusted clients or migrate to another remoting protocol. No indication of automatic mitigation or no-action is provided by the vendor.

Description

Apache TomEE versions using the embedded HTTP server to serve Hessian remoting endpoints silently ignore configured authentication and transport security. This allows remote unauthenticated attackers to invoke exposed EJB methods without credentials or encryption. The issue affects deployments relying on the embedded HTTP server rather than Tomcat. Users should block network access to Hessian endpoints from untrusted clients or migrate to a different remoting protocol.
