CVE-2026-29954
7.6 · HIGHOverview
CVE-2026-29954 is a high-severity vulnerability affecting cloudark kubeplus. It was published on March 30, 2026 and has a CVSS 3.1 base score of 7.6 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.6, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from cloudark. Update kubeplus to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
