In KubePlus 4.1.4, the mutating webhook and kubeconfiggenerator components have an SSRF vulnerability when processing the chartURL field of ResourceComposition resources. The field is only URL-encoded without validating the target address. More critically, when kubeconfiggenerator uses wget to download charts, the chartURL is directly concatenated into the command, allowing attackers to inject wget's option to achieve arbitrary HTTP header injection.
