CVE-2026-50236

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.

Affected Software

Weaknesses

• CWE-918: Server-Side Request Forgery (SSRF)

Workarounds

Apply NetworkPolicy egress restrictions to the openshift-console namespace to limit the console pod's outbound connectivity to required endpoints only (Kubernetes API server, OAuth server, monitoring). Note that a blanket default-deny egress policy will break console functionality. Monitor console access logs for unusual POST requests to /api/dev-console/webhooks/ paths with non-standard hostName values pointing to internal addresses or containing query separators.
