CVE-2026-86336: Apache TomEE EJB authorization bypass on JDK 21+

CVE-2026-86336 · Severity: info · Published 2026-11-10

Apache TomEE, an application server that runs Java enterprise applications, skips security checks on EJB (Enterprise JavaBeans) method calls when running on JDK 21 or later. This allows attackers to invoke protected EJB methods that should be restricted, potentially accessing or modifying sensitive business logic and data without proper authentication or authorization.

Technologies: Apache TomEE. Vendors: Apache.

Technical details

The vulnerability is an authorization bypass in EJB method access control that occurs specifically on JDK 21 and later. Callers can invoke EJB methods that have configured access restrictions without those restrictions being enforced, likely due to compatibility issues with newer Java versions. The attack requires network access to the TomEE instance and knowledge of the EJB methods to target.

Affected products

Apache TomEE all versions on JDK 21+
