CVE-2026-29954 NOMISEC HIGH WORKING POC
KubePlus 4.1.4 - chartURL Server-Side Request Forgery and Header Injection
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.
CVSS 7.6
CVE-2026-29955 NOMISEC HIGH WORKING POC
KubePlus < 4.2.0 - OS Command Injection via /registercrd chartName Parameter
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.
