@grpc/grpc-js: RBAC override configs in VirtualHost and Route resources are not applied
Medium (6.9) in grpc grpc-node. Fixed in @grpc/grpc-js-xds 1.14.2.
@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.

Explain CVE-2026-128065 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-128065?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-128065?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-128065 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.
