CVE-2026-50637 (GCVE-0-2026-50637)

Vulnerability from cvelistv5 – Published: 2026-06-10 18:32 – Updated: 2026-06-19 15:32

Title

Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections

Summary

Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections. The statsd protocol (and extensions) allow mutiple metrics, separated by newlines, to be sent per packet. The send method does not validate the contents of the metric names or values. If the names have newlines and statsd control characters (colon, pipe) then metric injections are possible. Version 0.04 fixed this by modifying the _make method to block metric names with characters below ASCII 32 (which includes the newline), or colons or pipes.

Vulnerability from github – Published: 2026-06-10 21:31 – Updated: 2026-06-19 18:32

Details

Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections.

The statsd protocol (and extensions) allow mutiple metrics,separated by newlines, to be sent per packet.

The send method does not validate the contents of the metric names or values. If the names have newlines and statsd control characters (colon, pipe) then metric injections are possible.

Version 0.04 fixed this by modifying the _make method to block metric names with characters below ASCII 32 (which includes the newline), or colons or pipes.

Severity

8.2 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
