Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, terminal websocket bootstrap routes only check authentication and do not enforce terminal authorization, allowing a low-privileged team member to connect to terminal routes and execute commands on team servers. This issue is fixed in version 4.0.0-beta.471.
