SSRF

Description

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 `--header` option to achieve arbitrary HTTP header injection.

Analysis

KubePlus 4.1.4 allows server-side request forgery (SSRF) and arbitrary HTTP header injection through improperly validated chartURL fields in ResourceComposition resources. The mutating webhook and kubeconfiggenerator components concatenate user-supplied chartURL values directly into wget command invocations without proper escaping, enabling attackers to inject wget options such as --header to forge HTTP requests or exfiltrate sensitive data. …
