| Description | AnyCable is a realtime server for reliable two-way communication that supports any backend. Prior to 1.6.15, the telemetry subsystem in telemetry/config.go enables tracking with a hardcoded public authToken, while clusterFingerprint in telemetry/telemetry.go reads the full configuration file and raw os.Args returned by anycableCLIArgs, including values supplied through --secret, --jwt_secret, and --http_rpc_secret. These inputs are passed to generateDigest, where sha256.New produces the hexadecimal fingerprint that is sent as telemetry. The available source therefore does not show raw credentials leaving the process or establish the advisory's claimed confidentiality loss, although the stable fingerprint is derived from secret-bearing configuration and the default telemetry client uses publicly known authentication material. This issue is fixed in version 1.6.15. |
