CVE-2026-26514

7.5 highEPSS 0.5%

High (7.5) in xddxdd bird-lg-go. EPSS 0.5% 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.
