A vulnerability has been found where an authenticated client can send a malicious XML-RPC request to supervisord that will run arbitrary shell commands on the server. The commands will be run as the same user as supervisord. Depending on how supervisord has been configured, this may be root.

DISPUTED In Supervisor through 4.0.2, an unauthenticated user can read log files or restart a service. Note: The maintainer responded that the affected component, inethttpserver, is not enabled by default but if the user enables it and does not set a password, Supervisor logs a warning message. The maintainer indicated the ability to run an open server will not be removed but an additional warning was added to the documentation.
