OPENEJB-HESSIAN · CVE-2026-97870 · Runtime
NO FIX YET · SEE WHAT TO DO
When Hessian remoting endpoints run on the embedded HTTP server, configured authentication and encryption requirements are silently not enforced. A remote attacker without credentials can call the exposed EJB methods, including over unencrypted connections.

Applications on Apache TomEE (or OpenEJB) that expose EJBs over Hessian remoting through the embedded OpenEJB HTTP server and rely on configured authentication or transport security for them. Those settings are silently ignored, so an unauthenticated remote caller can invoke the EJB methods, including over unencrypted connections. Deployments on Tomcat, or without Hessian endpoints, can skip it.

When Hessian remoting endpoints are served by the embedded HTTP server, configured authentication and transport security requirements are silently ignored. A remote unauthenticated attacker can invoke the exposed EJB methods without credentials or over an unencrypted connection. Only deployments that use the embedded HTTP server rather than Tomcat and rely on these settings are affected. Users are recommended to block network access to Hessian endpoints from untrusted clients, or to migrate to another remoting protocol.
