AI-suggested

A fix is available starting with Apache TomEE version 10.0.0-M1. Users should upgrade to this version or later to remediate the vulnerability. Until upgrading, it is recommended to block network access to Hessian endpoints from untrusted clients or migrate to another remoting protocol to prevent exploitation.

Description

CVE-2026-97874 is an improper authentication vulnerability in Apache TomEE when using Hessian remoting with BASIC authentication. The authentication check is bypassed for Hessian endpoints of applications deployed under a non-root context path, allowing remote unauthenticated attackers to invoke exposed EJB methods without credentials. Users are advised to restrict network access to these endpoints or migrate to a different remoting protocol.
