Title

Openshift/console: authenticated ssrf with full response reflection and path neutralization via dev console webhook helpers in openshift console

Summary

An authenticated SSRF flaw was found in the OpenShift Console Dev Console webhook helpers. User-supplied target URLs are fetched server-side without validation, with path neutralization enabling arbitrary endpoint targeting and full response reflection from the console pod's privileged network position.
