CVE-2026-50639 PEVANS CVE debrief

CVE-2026-50639 is a vulnerability in Metrics::Any::Adapter::SignalFx versions before 0.04 for Perl. The vulnerability occurs because the statsd protocol (and extensions such as dogstatsd) allow multiple metrics, separated by newlines, to be sent per packet. Metrics::Any::Adapter::SignalFx, which extends Metrics::Any::Adapter::Statsd, has a similar vulnerability. Additionally, the _labels function does not check tags labels newlines or statsd control characters, allowing for metric injections.
