DescriptionCVE.org

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.)

AnalysisAI

Metric and tag injection in the Perl DataDog::DogStatsd client (versions through 0.07) allows attackers who control event tag content to inject arbitrary metrics, tags, and event data into the DogStatsd telemetry stream. The CVSS 9.8 score reflects an unauthenticated network-vector CWE-93 (CRLF/separator injection) flaw where the format_event method fails to sanitize commas, newlines, pipes, and colons - including an ineffective s/|//g regex that misinterprets the pipe as a regex metacharacter. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Identify app forwarding user input to event tags
Delivery
Craft tag value with pipe/comma/newline separators
Exploit
Submit input through application interface
Execution
format_event serializes payload without sanitization
Persist
DogStatsd agent parses injected framing as legitimate metrics
Impact
Forged metrics/events poison DataDog telemetry pipeline

Vulnerability AssessmentAI

Exploitation Exploitation requires that the consuming Perl application calls DataDog::DogStatsd's event method (which invokes format_event) with tag values derived from attacker-controlled input - the vulnerability lives in the library but cannot be triggered without an application that passes untrusted data into tags. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The signals here conflict sharply and warrant careful interpretation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A web application using DataDog::DogStatsd records an event tag containing a user-supplied value such as a username or search term; an attacker submits a value containing pipes, commas, or newlines that, when serialized by format_event, are interpreted by the receiving DogStatsd agent as additional protocol framing. The result is forged metrics, fake events, or poisoned tags appearing in the victim's DataDog dashboards, potentially masking real alerts, triggering false ones, or polluting billing dimensions. …
Remediation No vendor-released patch identified at time of analysis - neither the CVE record nor the EUVD entry references a fixed version above 0.07, and the oss-security thread at https://seclists.org/oss-sec/2026/q2/827 should be monitored alongside CPAN for an updated release. … Detailed patch versions, workarounds, and compensating controls in full report.
