Summary
Some docker-compose files shipped by the Apache James project expose the WebAdmin REST API publicly by default, without proper authentication setup. This is an insecure default initialization (CWE-1188): the endpoints stay reachable until an operator configures credentials. Apache James versions from 0 before 3.9.1 are affected.

Description from the CNA
Some docker-compose shipped by the project exposes by default Webadmin REST API publically without proper authentication setup. Version 3.9.1 onward sets a random credential by default on unprotected webadmin endpoints to prevent this while retain convenience.
