CVE-2026-111257
Published:November 10, 2026
Updated:November 13, 2026
With the default configuration and no users defined in the default user database, TomEE silently adds an administrative user with a well-known password at startup. A remote attacker can use these credentials to authenticate to web applications that use the default realm and grant access to any authenticated user or to the TomEE administrative role. Users are recommended to upgrade to version 10.3.0 or 11.0.0-M2, which fix the issue.
