Command Injection in nvm via NVM_AUTH_HEADER in wget code path

A command injection vulnerability exists in nvm (Node Version Manager) versions 0.40.3 and below. The nvm_download() function uses eval to execute wget commands, and the NVM_AUTH_HEADER environment variable was not sanitized in the wget code path (though it was sanitized in the curl code path). An attacker who can set environment variables in a victim's shell environment (e.g., via malicious CI/CD configurations, compromised dotfiles, or Docker images) can inject arbitrary shell commands that execute when the victim runs nvm commands that trigger downloads, such as 'nvm install' or 'nvm ls-remote'.

OS命令中使用的特殊元素转义处理不恰当(OS命令注入)

Node Version Manager 安全漏洞

Node Version Manager是nvm.sh开源的一个节点版本管理器。 Node Version Manager 0.40.3及之前版本存在安全漏洞，该漏洞源于nvm_download函数使用eval执行wget命令且NVM_AUTH_HEADER环境变量未清理，可能导致命令注入。
