CVE-2026-111258: Apache TomEE: Security constraint bypass via request routing
The optional request routing feature forwards requests to their configured destination without applying the security constraints of that destination or the protection of the web application's private directories. If a route copies client-controlled parts of the request path into its destination, a remote attacker can reach protected resources or read application configuration and class files. Only installations with such a routing configuration are affected. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
