Xddxdd Bird-lg-go vulnerability

7.5 HIGHPublic exploitEPSS 0.65%
  1. Published4 Mar 2026

Description

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.
