CVE-2026-111256: Apache TomEE: Missing authentication for web service endpoints in embedded HTTP server
When JAX-WS or JAX-RS endpoints are published by the embedded OpenEJB HTTP server rather than Tomcat, some configured authentication methods are silently ignored and the endpoint is published without authentication. A remote unauthenticated attacker can invoke the exposed operations without credentials. Only deployments that use the embedded HTTP server and rely on such an authentication method are affected. Users are recommended to block network access to the embedded HTTP server from untrusted clients, or to migrate to the Tomcat based TomEE distributions.
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Block network access to the embedded HTTP server from untrusted clients.
- Compensating control
