CVE-2026-46720: CWE-93 Improper Neutralization of CRLF Sequences in RRWO Net::Statsd::Tiny
Net::Statsd::Tiny versions before 0.3.8 for Perl allowed metric injections. The metric names and set values were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics.
AI Analysis
Technical Summary
CVE-2026-46720 is a vulnerability in RRWO's Net::Statsd::Tiny Perl module prior to version 0.3.8. The issue is caused by improper neutralization of CRLF sequences (CWE-93) and related input validation failures (CWE-150) in metric names and values. This allows injection of additional statsd metrics by including newline, colon, or pipe characters in untrusted input. The vulnerability has a CVSS 3.1 score of 8.2 (high severity) with network attack vector, low attack complexity, no privileges or user interaction required, and impacts confidentiality and integrity but not availability.
Potential Impact
An attacker able to supply untrusted input to the vulnerable Net::Statsd::Tiny module can inject arbitrary statsd metrics. This can lead to manipulation or corruption of monitoring data, potentially misleading system administrators or automated systems relying on these metrics. The confidentiality impact is low, but integrity impact is high. Availability is not affected.
Mitigation Recommendations
No official patch or remediation level is currently documented. Users should upgrade to version 0.3.8 or later once available, as the vulnerability affects versions before 0.3.8. Until a fix is confirmed, avoid processing untrusted input through Net::Statsd::Tiny or implement input validation to reject newline, colon, and pipe characters in metric names and values. Monitor vendor advisories for official fixes.
