ApostropheCMS is an open-source Node.js content management system. Versions of the @apostrophecms/cli package up to and including 3.6.0 contain a command injection vulnerability in the apos create command. User-supplied input from the password prompt is embedded directly into a shell command without proper sanitization or escaping. This allows execution of arbitrary commands on the host system. As of time of publication, no known patched versions are available.
