Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Claude HUD是Jarrod Watts个人开发者的一个显示上下文使用、工具状态和进度的Claude Code插件。 Claude HUD 0.0.12及之前版本存在代码问题漏洞，该漏洞源于命令注入问题，可能导致本地攻击者通过操纵COMSPEC环境变量执行任意命令。攻击者可以在claude-hud执行版本检查前将COMSPEC设置为任意二进制路径，导致execFile()使用cmd.exe参数执行攻击者提供的可执行文件，在Windows系统上造成任意代码执行。

Vulnerability Title
Claude HUD 0.0.12 Arbitrary Command Execution via COMSPEC Environment Variable
Source: CVE Program / CVE List V5
Vulnerability Description
Claude HUD through 0.0.12, patched in commit 234d9aa, contains a command injection vulnerability that allows local attackers to execute arbitrary commands by manipulating the COMSPEC environment variable. Attackers can set COMSPEC to an arbitrary binary path before claude-hud performs its version check, causing execFile() to execute the attacker-supplied executable with cmd.exe arguments, resulting in arbitrary code execution on Windows systems.
