Summary
Red Hat OpenShift Container Platform 4.12, 4.14, 4.15, 4.16, 4.18 and other products are affected. The OpenShift console does not validate Helm chart URLs, which enables server-side request forgery (CWE-918). An authenticated console user with low privileges can make the console pod fetch arbitrary URLs, which can disclose sensitive information through error messages and allow blind port scanning inside the cluster.

Description from the CNA
A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster.
