Prior to 6.9.0, Centrifugo copies the client-controlled protocol.ConnectRequest.headers map through OnClientConnecting in internal/client/handler.go, ConnectEvent.Headers, and SetEmulatedHeadersToContext. The requestHeaders path in internal/proxy/http.go, the requestMetadata path in internal/proxy/grpc.go, and the Consume path in internal/unigrpc/grpc.go can forward an allowlisted value as a trusted backend header or metadata value. A remote client can spoof a header such as x-trusted-user for connect, refresh, subscribe, publish, RPC, and related proxy calls when the backend relies on that header for authentication or authorization. The unidirectional gRPC transport has no transport-level HTTP header that can override the emulated value. This issue is fixed in version 6.9.0.","state":0,"publishedAt":"2026-08-20T21:17:08.707+00:00","modifiedAt":"2026-10-18T20:10:00.11+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/centrifugal/centrifugo/commit/84d38cea1dd2efa24375a148817a974c8727f4b0","https://github.com/centrifugal/centrifugo/pull/1182","https://github.com/centrifugal/centrifugo/releases/tag/v6.9.0","https://github.com/centrifugal/centrifugo/security/advisories/GHSA-9468-v6mj-fppw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-71485","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-290"],"productCriteria":[],"sourceDates":{"published":"2026-08-20T21:17:08.707","lastModified":"2026-10-18T20:10:00.110"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
