CVE-2026-46739 Details
Description
Net::Statsd versions before 0.13 for Perl allow metric injections. The metric names are not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. The update_stats (used for updating counters) and gauge methods do not check that values are numeric (which would block metric injection).
A vulnerability allowing metric injection has been identified in Net::Statsd versions prior to 0.13 and in Net::Statsd::Lite versions prior to 0.9.0, both for Perl. The issue arises because metric names are not properly validated for newlines, colons, or pipes, allowing metrics from untrusted sources to inject additional StatsD metrics. Furthermore, the 'update_stats' and 'gauge' methods do not ensure that values are numeric, which could also facilitate metric injection.
Users can upgrade to Net::Statsd version 0.13 or later, or to Net::Statsd::Lite version 0.9.0 or later, to address this vulnerability.
