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":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":null}],"references":["https://github.com/centrifugal/centrifugo/security/advisories/GHSA-9468-v6mj-fppw","https://github.com/centrifugal/centrifugo/pull/1182","https://github.com/centrifugal/centrifugo/commit/84d38cea1dd2efa24375a148817a974c8727f4b0","https://github.com/centrifugal/centrifugo/releases/tag/v6.9.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-63649","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 20, 2026, 9:01:00 PM","dateUpdated":"Aug 25, 2026, 3:23:47 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
