CVE-2026-50637Network attack vector

Metric injection via unvalidated StatsD delimiters

Published Jun 10, 2026 · Updated Jun 10, 2026

Metric injection in Paul Evans Metrics::Any::Adapter::Statsd before 0.04 allows attackers to insert unauthorized metrics into StatsD packets. The send method passes metric names and values without validation, allowing newlines, colons, and pipes to be interpreted as protocol delimiters. Exploitation requires attacker-controlled metric data to reach send; injected records can corrupt downstream monitoring data.
