What is CVE-2026-29954?
CVE-2026-29954 is a high-severity server-side request forgery vulnerability in n/a, published on 30 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
