CVE-2026-11373

Net::Statsite::Client versions through 1.1.0 for Perl allow metric injections.

Net::Statsite::Client is a client for the statsite protocol, which is a variant of statsd.

Newlines are not removed from metric names, allowing metric injections.

Values are not sanitised for newlines or other protocol control characters such as colons or pipes, allowing metric injections.

Weakness

The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.
