CVE-2026-128065

@grpc/grpc-js: RBAC override configs in VirtualHost and Route resources are not applied

Published Nov 12, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed

Description

@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. From 1.14.0 through 1.14.1, XdsServer in @grpc/grpc-js-xds can acknowledge Route and VirtualHost resources while failing to apply their RBACPerRoute override configurations. The override parser is not registered under the override message type, override maps are stored under a type URL instead of the configured HTTP filter name, and VirtualHost override maps are not read. When experimental RBAC is enabled and a trusted xDS control plane supplies a broad top-level ALLOW policy with a stricter matching override, affected servers evaluate RPCs under the broad policy and can accept requests that should be denied. This issue is fixed in version 1.14.2.
