CVE-2026-11362: CWE-93 Improper Neutralization of CRLF Sequences in BINARY DataDog::DogStatsd
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.)
AI Analysis
Technical Summary
CVE-2026-11362 is a critical vulnerability in DataDog::DogStatsd (Perl) versions up to 0.07 where the format_event method does not properly sanitize event tag inputs. Specifically, the method allows injection of commas, newlines, pipes, and colons due to ineffective sanitization (notably an ineffective attempt to remove pipes using a faulty regular expression). This improper neutralization of CRLF sequences (CWE-93) and related input validation issues (CWE-150) enable attackers to inject malicious metrics from untrusted sources, potentially compromising the monitoring data's confidentiality, integrity, and availability.
Potential Impact
The vulnerability allows attackers to inject arbitrary metrics into DataDog::DogStatsd by exploiting unsanitized event tags. This can lead to manipulation or corruption of monitoring data, impacting the accuracy and reliability of metrics. The CVSS score of 9.8 indicates a critical impact on confidentiality, integrity, and availability without requiring privileges or user interaction.
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, avoid using untrusted input in event tags or implement custom input validation and sanitization to mitigate injection risks.
