CVE-2026-46740
Deferred Deferred - Pending Action
Metric Injection in Mojolicious::Plugin::Statsd

Publication date: 2026-05-26

Last updated on: 2026-05-28

Assigner: CPANSec

Description
Mojolicious::Plugin::Statsd versions through 0.04 for Perl allowed metric injections. The metric names and set values were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. Version 0.06 changes the module from being a statsd client to using a separate statsd client. It defaults to using a version of Net::Statsd::Tiny that fixes a similar issue (CVE-2026-46720).

Executive Summary

The vulnerability exists in Mojolicious::Plugin::Statsd versions through 0.04 for Perl, where metric names and set values were not properly checked for special characters such as newlines, colons, or pipes.

This lack of validation allows an attacker to inject additional statsd metrics by crafting metrics from untrusted sources, effectively enabling metric injection.

Impact Analysis

This vulnerability can impact you by allowing attackers to inject unauthorized metrics into your statsd monitoring system.

Such metric injections could lead to misleading monitoring data, potentially causing incorrect system behavior, misinterpretation of system health, or masking of real issues.

Mitigation Strategies

To mitigate this vulnerability, upgrade Mojolicious::Plugin::Statsd to version 0.06 or later. Version 0.06 changes the module to use a separate statsd client that addresses the metric injection issue by using a fixed version of Net::Statsd::Tiny.
