CVE-2026-50637 PEVANS CVE debrief

CVE-2026-50637 is a HIGH severity vulnerability in Metrics::Any::Adapter::Statsd versions before 0.04 for Perl. The vulnerability allows metric injections due to lack of input validation in the send method, enabling attackers to inject malicious metrics. The statsd protocol and its extensions permit multiple metrics, separated by newlines, to be sent per packet. If metric names contain newlines and statsd control characters (colon, pipe), injections are possible. Version 0.04 fixes this by modifying the _make method to block metric names with characters below ASCII 32 (including newlines), colons, or pipes.
