Description
org.apache.kafka.streams.processor.internals.RecordCollectorImpl leaks data on error as it dumps the value / message payload to the logs.
This is problematic as it may contain personally identifiable information (pii) or other secret information to plain text log files which can then be propagated to other log systems i.e Splunk.
I suggest the key, and value fields be moved to debug level as it is useful for some people while error level contains the errorMessage, timestamp, topic and stackTrace.
private <K, V> void recordSendError( final K key, final V value, final Long timestamp, final String topic, final Exception exception ) { String errorLogMessage = LOG_MESSAGE; String errorMessage = EXCEPTION_MESSAGE; if (exception instanceof RetriableException) { errorLogMessage += PARAMETER_HINT; errorMessage += PARAMETER_HINT; } log.error(errorLogMessage, key, value, timestamp, topic, exception.toString()); sendException = new StreamsException( String.format( errorMessage, logPrefix, "an error caught", key, value, timestamp, topic, exception.toString() ), exception); }
