Operators commonly use this to forward identity/trust headers to their own backend for access-control decisions.\n\nHowever, the wire protocol used by every Centrifugo transport (`protocol.ConnectRequest`, field `headers`) includes a `headers` map populated entirely from the connecting client's own message (its JSON `connect` command, or for gRPC, its `ConnectRequest` protobuf field) -- not from real t","public_affected_ranges":["<= 6.8.4"]}],"null_published_at":"2026-11-05T19:10:21.475Z","source_updated_at":"2026-09-17T16:35:35.000Z","source_disclosed_at":"2026-09-02T23:41:37.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T19:09:30.244Z"}],"next_cursor":null,"snapshot_revision":"42594"}
