AI-suggested

Upgrade to version 3.9.1 or later, which sets a random credential by default on unprotected Webadmin endpoints, effectively mitigating the risk. No additional action is required if using these versions.

Description

Certain docker-compose files shipped by the project expose the Webadmin REST API publicly by default without proper authentication. Starting with version 3.9.1, the project mitigates this by setting a random credential on unprotected Webadmin endpoints to prevent unauthorized access while maintaining convenience.
