CVE-2026-9270 analysis covering impact, affected products, versions, remediation, and cross-checked defender guidance.
CVE-2026-9270 is a vulnerability published by NVD on 05/06/2026.
What happened
DataDog::DogStatsd versions through 0.07 for Perl allow metric injections.
DataDog::DogStatsd does not properly sanitise input, allowing metric injections of data from untrusted sources.
The send_stats method does not remove newlines from metric names ($stat variable), allowing attackers to change the metric name prefix.
The send_stats method does not validate the content of the value ($delta variable), allowing attackers to inject metrics, especially from methods that do not restrict the data type for the value, such as set, gauge, count and histogram.
The send_stats method does not validate the content of the tags, which may contain newlines, pipes and colons that allow metric injections.
Note that the SYNOPSIS shows an example of passing a website form "loginName" parameter as a tag, which is unsafe.
