The go-control-plane xDS server exposes both streaming and unary (Fetch) RPC methods for all registered discovery services. Since there is no unary interceptor, these Fetch endpoints are completely unauthenticated. \n\nAdditionally, the JWT authentication interceptor in GatewayNamespaceMode only validates tokens when the received gRPC message is of type `discoveryv3.DeltaDiscoveryRequest` . If the message is a `discoveryv3.DiscoveryRequest` — used by the State-of-the-World (SotW) xDS protocol — the type assertion fails, the validation block is skipped entirely, and RecvMsg returns nil (success) without any authentication.\n\nAny pod in the cluster that can reach the xDS server (port 18000) can use the SotW protocol to bypass JWT authentication and access:\n\n* TLS private keys via StreamSecrets (SDS)\n* All xDS resources via StreamAggregatedResources (ADS)\n* Backend endpoints via StreamClusters / StreamEndpoints (CDS/EDS)\n* Routing rules via StreamRoutes / StreamListeners (RDS/LDS)\n\n### Credits\n\nEnvoy Gateway thanks @dashingDragon and @Donjon-Cerberus for reporting this issue.","state":0,"publishedAt":"2026-07-16T19:32:23+00:00","modifiedAt":"2026-09-21T09:40:34.2827109+00:00","affected":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"1.8.0-rc.0"},{"kind":"fixed","version":"1.8.1"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.7.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/envoyproxy/gateway/security/advisories/GHSA-22xc-xg2r-9j7v","https://github.com/envoyproxy/gateway"],"sourceUrl":"https://github.com/advisories/GHSA-22xc-xg2r-9j7v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-22xc-xg2r-9j7v","identifiers":["GHSA-22xc-xg2r-9j7v","BIT-envoy-gateway-2026-53714","CVE-2026-53714","GO-2026-6003"]},"retained":false,"historicalAffected":[]},{"revision":"430c45eb6598448f9dbfbc57d3c9aeb5","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6003","aliases":["BIT-envoy-gateway-2026-53714","CVE-2026-53714","GHSA-22xc-xg2r-9j7v"],"title":"Envoy Gateway: xDS Control Plane Information Disclosure when operating in GatewayNamespaceMode in github.com/envoyproxy/gateway","description":"Envoy Gateway: xDS Control Plane Information Disclosure when operating in GatewayNamespaceMode in github.com/envoyproxy/gateway","state":0,"publishedAt":"2026-07-17T19:42:05+00:00","modifiedAt":"2026-09-21T09:40:34.2827109+00:00","affected":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.7.4"},{"kind":"introduced","version":"1.8.0-rc.0"},{"kind":"fixed","version":"1.8.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/envoyproxy/gateway/security/advisories/GHSA-22xc-xg2r-9j7v"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6003","license":"OSV · upstream source license applies","key":"osv:GO-2026-6003","identifiers":["GO-2026-6003","BIT-envoy-gateway-2026-53714","CVE-2026-53714","GHSA-22xc-xg2r-9j7v"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
