CVE-2026-50639

Metrics::Any::Adapter::SignalFx versions before 0.04 for Perl does not protect against metric injections. The statsd protocol (and extensions such as dogstatsd) allow mutiple metrics, separated by newlines, to be sent per packet. Metrics::Any::Adapter::SignalFx which extends Metrics::Any::Adapter::Statsd, which has a similar vulnerability. In addition, the _labels function does not check tags labels newlines or statsd control characters. The labels can be used for metric injections.

Summary		(es) Las versiones de Metrics::Any::Adapter::SignalFx anteriores a la 0.04 para Perl no protegen contra inyecciones de métricas. El protocolo statsd (y extensiones como dogstatsd) permiten que múltiples métricas, separadas por saltos de línea, sean enviadas por paquete. Metrics::Any::Adapter::SignalFx, que extiende a Metrics::Any::Adapter::Statsd, que tiene una vulnerabilidad similar. Además, la función _labels no verifica los saltos de línea en tags o en rótulos, ni los caracteres de control de statsd. Las etiquetas pueden ser utilizadas para inyecciones de métricas.
