CVE-2023-26269

Estado: ModificadaAlta (7.8)—

Apache James server version 3.7.3 and earlier provides a JMX management service without authentication by default. This allows privilege escalation by a malicious local user.

Administrators are advised to disable JMX, or set up a JMX password.

Note that version 3.7.4 onward will set up a JMX password automatically for Guice users.
