/*
* 漏洞标题：Birth Chart Compatibility WordPress插件2.0 - 完整路径泄露
* 作者：Byte Reaper
* Telegram：@ByteReaper0
* CVE编号：CVE-2025-6082
* 软件链接：https://frp.wordpress.org/plugins/birth-chart-compatibility/
* 漏洞描述：此概念验证利用"Birth Chart Compatibility" WordPress插件（版本<=2.0）的完整路径泄露漏洞。它向插件的index.php端点发送HTTP GET请求，
* 捕获返回的PHP警告或致命错误，并解析服务器的文件系统路径（如"/var/www/html/wp-content/plugins/…"或"C:\\xampp\\htdocs\\…"）。
* 泄露此路径有助于攻击者进行进一步的LFI/RCE或侦察攻击。
