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

Wazuh 从 4.1.0 到 4.14.8（不含 4.14.8）版本中存在一个缺失的源地址检查漏洞，位于 wm_agent_upgrade 模块。该漏洞允许已注册的代理（enrolled agents）向服务器发送带有攻击者可控的 file_path 参数的 upgrade_custom 命令。攻击者可通过在代理通道中注入恶意的 upgrade_custom 消息，以 root 权限读取任意文件，从而泄露 /etc/shadow 和 client.keys 等敏感文件。
