Prior to 1.7.4 and 1.8.1, the xDS gRPC server in GatewayNamespaceMode, configured through provider.kubernetes.deploy.type=GatewayNamespace, installs a JWT StreamInterceptor but no UnaryInterceptor, leaving every unary Fetch RPC unauthenticated. The streaming interceptor also authenticates only discoveryv3.DeltaDiscoveryRequest messages; a discoveryv3.DiscoveryRequest used by the State-of-the-World protocol fails the type assertion and returns success without JWT validation. Any pod that can reach port 18000 can use the unauthenticated unary or State-of-the-World paths to retrieve TLS private keys through StreamSecrets, all xDS resources through StreamAggregatedResources, backend endpoints through StreamClusters or StreamEndpoints, and routing configuration through StreamRoutes or StreamListeners. This issue is fixed in versions 1.7.4 and 1.8.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":7.4},"cwes":["CWE-306"],"references":["https://github.com/envoyproxy/gateway/commit/4df0809ff1ed59ffb09604da4084335b8c6647c5","https://github.com/envoyproxy/gateway/commit/e9124abc4ff4b63a218a6890c1b28a982c850465","https://github.com/envoyproxy/gateway/commit/f1f9829af2a231f0cae915c09800353c76622d97","https://github.com/envoyproxy/gateway/pull/8986","https://github.com/envoyproxy/gateway/pull/9116"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-53714","score":0.00348,"percentile":0.2811,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-22xc-xg2r-9j7v","url":"https://osv.dev/vulnerability/GHSA-22xc-xg2r-9j7v","summary":"Envoy Gateway: xDS Control Plane Information Disclosure when operating in GatewayNamespaceMode ","modified":"2026-09-21T09:40:34.282710915Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":[">=1.8.0-rc.0 <1.8.1"],"fixed":["1.8.1"]},{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.7.4"],"fixed":["1.7.4"]}]},{"id":"GO-2026-6003","url":"https://osv.dev/vulnerability/GO-2026-6003","summary":"Envoy Gateway: xDS Control Plane Information Disclosure when operating in GatewayNamespaceMode in github.com/envoyproxy/gateway","modified":"2026-09-21T09:40:34.282710915Z","packages":[{"ecosystem":"Go","name":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","ranges":["<1.7.4",">=1.8.0-rc.0 <1.8.1"],"fixed":["1.7.4","1.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
