The /registercrd endpoint in KubePlus 4.14 in the kubeconfiggenerator component is vulnerable to command injection. The component uses subprocess.Popen() with shell=True parameter to execute shell commands, and the user-supplied chartName parameter is directly concatenated into the command string without any sanitization or validation. An attacker can inject arbitrary shell commands by crafting a malicious chartName parameter value.
