Overview
Affected versions of this package are vulnerable to CRLF Injection through DatadogStatsdLineBuilder, EtsyStatsdLineBuilder, and the Printer in LoggingMeterRegistry. An attacker can spoof metrics or log entries by supplying meter names, tag keys, or tag values containing \n or \r, causing the generated StatsD or log output to break into additional lines.
