Metric Injection in DataDog DogStatsd Perl Library

Publication date: 2026-06-05

Last updated on: 2026-06-10

Assigner: CPANSec

Description
DataDog::DogStatsd versions through 0.07 for Perl allow metric injections from event tags. DataDog::DogStatsd does not properly sanitise input, allowing metric injections of data from untrusted sources. The format_event method (used by the event method) does not validate the content of the tags, which may contain commas (allowing tags to be injected) or newlines, pipes and colons that allow metric injections. (There is an ineffective s/|//g to remove pipes, but because the pipe is not escaped, it is interpreted as a regular expression metacharacter and has no effect.)

CWE ID Description
CWE-150 The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component.
CWE-93 The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.

Executive Summary

This vulnerability exists in DataDog::DogStatsd versions through 0.07 for Perl, where the software does not properly sanitize input from event tags.

Specifically, the format_event method used by the event method fails to validate the content of tags, allowing malicious input containing commas, newlines, pipes, and colons.

Because of this improper sanitization, attackers can perform metric injections by injecting additional tags or metrics through untrusted data sources.

An attempted removal of pipe characters is ineffective due to incorrect use of regular expressions, which means pipes can still be used to inject metrics.

Impact Analysis

This vulnerability can allow attackers to inject false or misleading metrics into the monitoring system by exploiting untrusted event tags.

Such metric injections can corrupt monitoring data, potentially leading to incorrect alerts, misinterpretation of system health, or masking of real issues.

This can impact decision-making processes that rely on accurate metrics and may reduce the reliability of monitoring and alerting systems.
