Overview
Affected versions of this package are vulnerable to Command Injection via the POST /api/v1/cron process. An attacker can execute arbitrary shell commands on all servers across tenants by creating a scheduled cron task with specific parameters, causing the command to be pushed and executed on every server, including those belonging to other tenants. The output is then sent to an attacker-controlled webhook.
