CVE-2026-26514: Xddxdd Bird-LG-Go

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

An Argument Injection vulnerability exists in bird-lg-go before commit 6187a4e. The traceroute module uses shlex.Split to parse user input without validation, allowing remote attackers to inject arbitrary flags (e.g., -w, -q) via the q parameter. This can be exploited to cause a Denial of Service (DoS) by exhausting system resources.

Affected products
