A Server-Side Request Forgery and supply chain flaw was found in the OpenShift Console Helm catalog proxy. A namespace tenant can plant a ProjectHelmChartRepository with an arbitrary URL that the console pod fetches server-side, bypassing tenant egress restrictions. Combined with catalog metadata poisoning and admin-mediated chart installation, this enables privilege escalation.

Solution

No solution given by the vendor.


Workaround

Review existing ProjectHelmChartRepository resources in tenant namespaces for unexpected URLs using: oc get projecthelmchartrepositories --all-namespaces -o jsonpath='{range .items[*]}{.metadata.namespace}/{.metadata.name}: {.spec.connectionConfig.url}{"\n"}{end}'. Apply NetworkPolicy egress restrictions to the openshift-console namespace (note: requires allow-listing required console egress targets). Administrators should verify chart provenance before installing Helm charts from namespace-scoped repositories. Disable or restrict ProjectHelmChartRepository creation via RBAC if namespace tenants do not require custom Helm repositories.
