Affected versions of this package are vulnerable to Remote Code Execution (RCE). Features considered dangerous (which could be used for remote code execution) can be configured in a ConfigSet that's uploaded via API without authentication or authorization. The checks in place to prevent such features can be circumvented by using a combination of the UPLOAD and CREATE actions.
