CVE-2026-50637 Details
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.
A vulnerability in Metrics::Any::Adapter::Statsd for Perl, affecting versions prior to 0.04, allows for metric injections. The issue arises because the send method does not validate metric names or values, leaving room for newlines and statsd control characters (colons and pipes) to be exploited. This vulnerability could be reproduced by sending metrics from untrusted sources that include these characters, injecting additional statsd metrics.
Users can upgrade to Metrics::Any::Adapter::Statsd version 0.04 or later, which addresses this vulnerability by blocking metric names with disallowed characters, including newlines, colons, and pipes.
