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."}], "lastModified": "2026-03-30T19:16:24.890", "sourceIdentifier": "cve@mitre.org"}
