CVE-2026-46719Network attack vector

Metric forgery via delimiter injection

Published May 16, 2026 · Updated May 16, 2026

Metric injection in Net::Statsd::Lite before 0.9.0 allows attackers to forge StatsD metrics through untrusted metric names. The record_metric method concatenates unchecked metric names into protocol records, letting newline, colon, or pipe characters create extra fields or records. Reachability requires a consuming application to pass attacker-influenced metric names, enabling falsified monitoring data.
