Q: How do I fix CVE-2026-50637?

Upgrade metrics\ to 0.04 or later.

Q: Is CVE-2026-50637 being actively exploited?

Not that we know of. CVE-2026-50637 is not in the CISA Known Exploited Vulnerabilities catalog. Its EPSS score of 0.32% is the estimated probability that it will be exploited in the next 30 days. That is higher than 25% of all scored CVEs.

Q: How severe is CVE-2026-50637?

CVE-2026-50637 has a CVSS v3 base score of 8.2, rated high. CVSS rates the technical impact if the vulnerability is exploited, not how likely that is, so weigh it alongside the exploit-prediction score when you decide what to patch first.

Q: What does CVE-2026-50637 affect?

Published advisories record a fix for metrics\ (NVD). Only products with a sourced advisory are listed, so treat this as what we can cite rather than a complete inventory.

NVD

Description

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.
