CVE-2026-8788: CWE-93 Improper Neutralization of CRLF Sequences in RRWO Net::Statsd::Lite
Net::Statsd::Lite versions through 0.10.0 for Perl allowed metric injections. The values from the set_add method were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. Note that version 0.9.0 fixed a similar issue CVE-2026-46719 for metric names.
AI Analysis
Technical Summary
CVE-2026-8788 describes a vulnerability in Net::Statsd::Lite (Perl) where the set_add method does not properly sanitize input values for newlines, colons, or pipe characters. This improper neutralization of CRLF sequences (CWE-93) enables attackers to inject additional statsd metrics, potentially manipulating monitoring data. The vulnerability affects versions through 0.10.0. A related vulnerability affecting metric names was addressed in version 0.9.0, but this injection vector remains unpatched. No vendor advisory or patch is currently available to confirm remediation status.
Potential Impact
An attacker can inject arbitrary statsd metrics by supplying crafted input to the set_add method, potentially corrupting monitoring data integrity and causing misleading metrics. The CVSS score of 7.3 (high) reflects the network attack vector, low complexity, no privileges required, and impacts on confidentiality, integrity, and availability of monitoring data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid using untrusted input in the set_add method or apply custom input validation to reject newlines, colons, and pipe characters in metric values.
